At the China International Optoelectronics Summit Forum held on the morning of September 9, 2020, Academician Jiang Huilin of the Chinese Academy of Engineering released the wonderful report of Research on the Development Trend of Advanced Optoelectronics Technology.
Academician Jiang said that in the 1970s, Academician Qian Xuesen said that optoelectronics in the 21st century would be developed by leaps and bounds like the electronic technology in the 20th century.
In the 1990s, the US Department of Commerce once wrote an article pointing out that whoever takes the initiative in photoelectric technology will win in the cutting-edge scientific competition in the 21st century. In June 2000, Japan's Shout magazine commented that the first leading industry with representative significance in the 21st century is the photoelectric industry.
Academician Wang Daheng, China's optical magnate, said that optoelectronic technology in the 21st century will grow at the explosive speed multiplied by years; As we all know, microelectronics technology in the 20th century has doubled in a year and a half in accordance with Moore's Law. Photoelectric instruments are multipliers of industrial production, pioneers of scientific research, combat effectiveness of national defense and military, and materialization judges of social life. Later, it was further clarified that optics is old and new, with a promising future.
In view of the future development trend of advanced optoelectronic technology, Academician Jiang summarized five trends: "five new", "five special", "five more", "five modernizations" and "five domains".
1、 "Five New"
New materials, new processes, new devices, new mechanisms and new methods.
1. New materials.
In 2017, there was a case in the United States. Now, advanced semiconductor materials have special characteristics. A new class of semiconductor materials was introduced, which not only enhanced the function of photovoltaic devices and solar panels, but also saved 100 times the amount of materials compared with conventional ones. I want to save at least 10 times.
2. New process.
The new optical fiber manufacturing process of the Massachusetts Institute of Technology in the United States will implant high-speed optoelectronic semiconductor devices into the fabric.

The super-resolution imaging lithography equipment of the Institute of Optoelectronics of the Chinese Academy of Sciences has made photolithography devices. Under the wavelength of 365nm, the processing of sizes below 10nm has been achieved very well, and it has also been used in aerospace.
4. New mechanism.
Laser communication is very popular in the world now. Unfortunately, every country in the world is one-to-one, and it has not been used in many fields until now. Changchun University of Technology has invented a special optical antenna, and the device has also been made. Therefore, the expert evaluation is first proposed at home and abroad.
5. New methods.
In 2013, the "pillar" micro interferometric optical imaging project in the United States, an array composed of hundreds of lenses with a diameter of 1mm, not only has its size and weight improved a lot compared with traditional telescopes, but also its resolution has been improved by more than 10 times, which has also passed ground simulation experiments.
Changchun Institute of Optics and Mechanics has put forward a method that stagger the quarter position, and the theoretical resolution can be improved by 2 times, but actually it is also improved by 1.8 times. This is a new method.
Beijing University of Technology has put forward a new method for precise measurement of complex surfaces, which is a combination of virtual and real, and is a transient interference method. At the same time, the error of refraction radius of deformed materials and the surface itself has also been reduced, so the measurement is still very good.
2、 "Five Specialties"
Super small, super large, super fine, super fast, super high.
1. Very small.
Australia's satellite optical structure nano sensor has been developed and can be implanted into human wearing devices to help doctors detect.
The "ant colony" micro robot developed by HIT is 3 microns long and 2 microns in diameter, which is very useful.

Our country has carried the No. 20 satellite, and the ground communication has reached 10G. At present, it is the most widely used space communication.
3、 "More than five"
Multi frontier, multi-dimensional, multispectral, multi-functional, multidisciplinary.
1. Multi frontier.
On July 23 this year, our country's Long March 5, China's first active exploration mission, "Tianwen 1", launched a medium and high resolution camera to image the surface of Mars. The second is to detect the magnetic field environment, as well as spectral analyzer, which mainly analyzes the mineral composition of Mars. The European Space Agency's "Mars Express" took large-scale, three-dimensional photos on the surface of Mars.
2. Multidimensional.
Northwest Agricultural University of the United States uses compressed hyperspectral polarization imaging to obtain the quantum of intensity, spectrum and polarization of the target. These latitudes have been obtained, and the polarization is a full time spectrum.
In 2018, Changchun University of Science and Technology combined bionic technology with optical technology, made the micro structure of moth eye, and studied lobster eye and other aspects.
The infrared polarization composite imager made in Arizona, the United States, also achieved full polarization.
3. Multispectral.
The United States Navy is equipped with photoelectric multi spectral aiming system, multi spectral sensors, near-infrared and other supporting equipment. The full spectrum imager of the 11th Research Institute of CETC has been used on Gaofen No. 5, and the visible infrared is available.
Switzerland has released the world's smallest and lightest multi spectral UAV sensor, which has a wide range of applications, including green light, yellow light, infrared, near-infrared, and many military applications.
4. Versatility.
NASA launched the lunar atmosphere and dust environment probe to the moon, and the environmental ranging and communication functions have been realized.
Changchun University of Science and Technology, Xi'an Jiaotong University and the National Astronomical Observatory carried out research on space-based space debris measurement, integrated communication design and other technologies.
5. Multidisciplinary.
South Korea has released a computer optometer, which combines optical technology, imaging technology and eye monitoring technology. This instrument is very useful in human detection, especially computer optometry, which is very convenient to use.
The Key Laboratory of Computational Optics of the Chinese Academy of Sciences, the first computational super-resolution imaging system and optical imaging payload in China, has done a good job. The orbital height at 700KM is from 2.8m to 1.4m, doubling the resolution. Inherited from the State Key Laboratory of Optics, microwave photonics has been established by combining microwave and laser. Their band ranges from 0.8 to 31.1GHz, and filtering has been realized.
4、 "Five Modernizations"
Informatization, networking, automation, digitization and intelligence.
1. Informatization.
A glass production line in Germany is equipped with thousands of optical sensors. No one is seen in the whole space. The whole space is information-based management, so they say it is an information-based workshop. Changchun University of Science and Technology has developed the information system inside and outside the vehicle. For example, in terms of residential buildings, how the environment is, how the operation is, and whether there are other disturbances around, you can see these data parameters.
2. Networking.
The plan of the United States combines radio frequency lasers to build an integrated network of sky, earth and sea. In 2018, our country has decided to build the network into an integrated network with more than 800 satellites, four major system network technology systems, network security systems, network standard systems, and network policy systems. At the meeting held in Finland, Huawei, a Chinese company, proposed that the Internet of Things (IOT), which is more than 5G in the 6G era, is the Internet of Everything. Now the world also attaches great importance to it.
3. Automation.
The United States proposed to develop the strongest auto drive system, and they made no secret of it. With the power of optics, it is safer to operate than the previous generation. The University of National Defense Science and Technology has developed driverless cars, and it has done a good job.
The 61 Institute of the General Staff realized the round trip unmanned experiment from Beijing to Tianjin and from Beijing to Zhengzhou, and achieved complete success. The robot vision inspection technology in China has been used for the automatic inspection of automobile parts, which has also been done very well, with automatic inspection reports and automatic management.
4. Digitize.
The digital camouflage system released by the United States is mainly to confuse the other party. If you engage in artificial intelligence, I will do it. Seeing that fighter planes are like clouds, they confuse the AI system. They can't identify tanks or unmanned vehicles, or they are invisible, so there is always a spear and a shield.
Shanghai Institute of Optics has made outstanding achievements in digital precision diagnosis of laser beams, combining coded beam splitting and phase recovery algorithms. The new digital reconnaissance system for individual soldiers made in Switzerland has many functions integrated together. It is also used in combination with the digital map of individual soldiers. The whole digitization has been obviously used.
5. Intelligence.
The Massachusetts Institute of Technology combines artificial intelligence with optical technology to enable intelligent robots to check random objects they have never seen before. In many fields, it has completely changed the labor level of existing robots.
The team members of China's photon artificial intelligence chip are doctoral students from Tsinghua University, Peking University and Beijing Jiaotong University. The design, processing, packaging and testing of this chip are all completed in China.
At that time, it was evaluated as overtaking at the curve, catching up with the world or leading level. Israel has a smart gun sight, which can capture targets in the market. In terms of automation, it has taken a big step forward.
5、 Five Domains
Space exploration, ocean exploration, photoelectric display, medical health, smart city.
1. Space exploration.
This is the space tracking and surveillance system plan of the United States. This year, the low orbit target positioning accuracy will reach 10 meters, and the high orbit positioning accuracy will reach 100 meters. This is an amazing accuracy. Our country still has a big gap at present. In 2019, China's Chang'e-4 will be on the back of the moon, doing creative work. It was L2 that carried out measurement and control and relay communication, and sent back the image map of the back of the moon taken at close range in the first chapter of the world.
Changchun Institute of Optics has also done a very good job on wide format cameras in the past five years. At the height of 850KM, it is a space multispectral camera with super wide format.
2. Ocean exploration.
American lidar detects relevant indicators of algae and plants in the ocean. The algae inside are sensed by emitting laser pulses, etc. The indicators show that the ocean depth detected by lidar is much higher than that detected by satellite remote sensing, which is three times of the latter.
The "Haidou" submersible researched by Shenyang Institute of Automation has the largest diving depth of 10767 meters, and we have the third 10000 meter class unmanned submersible in the world.
3. Photoelectric display.
South Korea is made of hologram display technology. The distance between large format cameras has reached the micron level, and the pixel size has exceeded 25000 ppi, which should be said to be a great progress.
Beijing University of Technology has successfully developed a prototype of optical system splicing helmet and geometric wave to ultra-thin head mounted display.
4. Medical health.
The new photoelectric electrocardiograph made by Japan Broadcasting and Television Corporation, which uses photoelectric technology and powerful analysis programs, is still well done. It is a highly automated photoelectric body detection device that can print the results of ECG signals, which is very useful.
5. Smart City.
New York City has done a lot of work, changing the old toll telephone hall into a smart screen, and has developed into the largest wifi network in the city, installing electronic detectors, real-time detection of traffic in the area, etc. Intelligent transportation has made a great step forward.
Our country is Shenzhen. The first is information infrastructure, strengthening the integration of big data, artificial intelligence, Internet of Things and other information technologies, urban comprehensive information data platform, high-speed broadband network, comprehensive detection and perception system, urban big data, urban operation management, and smart public services. The goal is very clear, that is, a comprehensive perception of the map. The number one travel around Shenzhen, one click to know the overall situation, integrated operation and linkage, one-stop innovation and entrepreneurship, and a screen of intelligent life.
Hangzhou has also been rated as the most intelligent city in the white paper of China's New Smart City. The smart transportation is built by using the city's smart brain, and the effect is very good. These data will not be mentioned, and the face payment is also ahead.
In conclusion, the General Secretary pointed out that we should seize the opportunity of the integrated development of digitalization, networking and intelligence, and use informatization and intelligence as leverage to cultivate new momentum. Informatization has become the mainstream of the world's development. Let's continue to work hard, climb the peak, and strive to promote the development of photoelectric technology, so as to contribute to informatization, intelligence and human social progress.
