The optical characteristics of the infrared system are introduced. The laser beam produced by the typical infrared system of laser irradiation is verified theoretically and experimentally. The efficiency and spot size of the laser produced by the optical elements in the infrared system were measured experimentally, and the recognition of the laser spot was analyzed. The research results have certain practical significance to make full use of the back-projection laser to carry out the active laser tracking of the infrared system and recognize the closed-loop.
