The purpose of the research on military optoelectronic materials is to apply the research results to a new generation of high-tech optoelectronic equipment systems and to improve the capabilities of electronic offensive and defense integrated electronic warfare. Military optoelectronic materials are an important foundation of military optoelectronic technology, and have an important enabling and multiplying effect on military optoelectronic equipment systems. The photoelectric imaging night vision technology based on infrared materials can enhance the night combat capability of tanks, armored vehicles, aircraft, warships and infantry, and provide important means for aviation, satellite reconnaissance and early warning. Laser ranging, laser blinding weapons, and fire control systems based on new solid-state laser materials have greatly enhanced combat capability. Tunable laser crystals provide working materials for tunable laser systems from visible to infrared bands, which can improve the field surveillance and reconnaissance capabilities of military laser systems such as lidar, air sensing, and underwater detection. Using the advantages of optical fiber materials, broadband, anti-electromagnetic and strong nuclear electromagnetic pulse interference, secrecy, small size, strong environmental adaptability and anti-irradiation, it is possible to realize the GB/ between the unmanned long-range sensing array of the ground weapon system and the manned control station. S-class information transmission; ship commanders can send signals to long-distance fleets through optical fibers for command; airborne unmanned augmented aircraft or target planes that can launch fiber-optic cables; the wired guidance of weapons in the past will be replaced by fiber-optic guidance; the inertial navigation system of military carriers will be replaced by fiber-optic gyroscopes; and the C3I system launched by strategic weapons will also enable the fiber-optic C3I network, and so on. In short, the application of military fiber optic systems will go far beyond the scope of voice and low-rate data communications, and enter sensing, maritime or air weapon platforms, and various high-speed transmission systems.
