The high-tech and low-tech optical military instruments developed in mainland China can be counted, and many of them are excellent. Only the political turmoil at that time, coupled with too many research projects, insufficient funds, and failure to effectively cooperate with the strategic principles and policies, slowed down the development speed of China's military optical equipment in the middle of 1960, but there were still occasional masterpieces. Only 1970 troops were equipped with 10 active infrared observation sights, but this equipment was replaced by the first generation of low-light-level night vision devices at that time. At present, China's night vision technology still lags behind big countries for more than ten years, but its development speed has accelerated in the past 10 years.

Development and Application of Laser Components The world's first ruby laser was born in the United States in 1960. In the second year, Changguang Institute developed similar products with more advanced structure. At that time, several units were engaged in this work at the same time. Due to the breakthrough of this achievement, the article on promoting laser has received more attention. After measuring the technological progress at home and abroad, China executives were greatly encouraged and determined to develop laser equipment. 1965, aluminum garnet laser crystal was made by Southwest Institute of Technical Physics, and YAG laser was developed in the following year. 1972, QYAG laser with high repetition rate was successfully developed. The semiconductor laser for military optical fiber communication was also developed in the middle of 1960. In the past 20 years, China has successively developed CO2 laser, argon ion laser, ring laser, frequency stabilized laser and far infrared laser. In the middle of 1970, mass production of systems for army weapon ranging, ballistic measurement, satellite ranging, atmospheric laser communication, optical fiber communication, naval weapon ranging and army and air force weapon guidance began.

For example, 1974, Beijing Institute of Technology and other units began to explore laser semi-active guidance technology, and made a prototype in 1977. At present, the Air Force has equipped several kinds of laser-guided bombs, which are mainly used for the J-5 attack aircraft. The scheme of laser-guided anti-tank missile is formulated in 1983. At present, the first generation of this weapon has initially achieved mass production capacity and is called Lightning 1 Missile. A second generation of similar missiles is also under development. In addition, China also developed QYGA laser together with foreign countries, which made it realize laser drilling of gem bearings very early, and laser ranging and laser communication also developed rapidly. The optical fiber digital data bus for new equipment has been successfully developed, which can replace the existing 1553B data bus. As for the optical transmission control system on the fighter, the initial development stage has also been completed.
