Design and Fabrication of Near Space Laser Communication Link Optical System Filter Film
In order to improve the signal-to-noise ratio of the near space laser communication and avoid interference from stray light, we often use filters to filter and collect the signal. According to the parameter requirements of filters in the communication system, we select appropriate film materials with the preparation technology to design the film system. Electron beam heating evaporation and ion-assisted deposition system are adopted for film preparation. Using the film system′s evaluation function and the mathematical model related to the film sensitivity, the sensitivity of the film is optimized. The filters meet the requirements of the use of near space laser communication link optical system, and pass the environmental testing.
