Optical landing aid system simulator

When the carrier aircrafts land on the ship, carrier optical landing aid system is required on occasion. The lamp simulator used halogen tungsten light as light source, and a light uniformizer was added beside the light source. Then the beam shaping conical cavity was added according to the distribution of outgoing beam of light source. According to the demand of field angle, a cylinder array optical system was added at a certain distance. Then optical filter and optical attenuator were added at the exit pupil of the simulator. The lamp simulator had red, yellow, green spectrum, the horizontal field angle was 30 degree, the vertical field angle was 20 degree, the light intensity was over 10 000 cd, the uniformity of the lamphouse was better than 8%, and the light intensity was adjustable.
