OPTICAL MATERIALS FOR PASSIVE SURVEILLANCE SYSTEMS
As a result of the reduced visibility of modern air and sea objects, interest in passive surveillance and recognition systems, the main element of which is the optoelectronic system, has increased. Quartz glasses are used as materials in the optical system, but they have limitations on the transmission of electromagnetic radiation in the mid-infrared range, which reduces their efficiency. Advanced passive surveillance systems require materials with an extended transmission range of electromagnetic radiation in the infrared, visible, and ultraviolet ranges. One of the solutions to this problem can be the introduction of new materials in the optoelectronic system, such materials can be multicomponent fluoride glasses, taking into account their optical and thermomechanical characteristics, which can simultaneously perceive information about targets in various areas of the infrared range, including in the far infrared region.
