Design of the Moon Simulator with Large Diameter Based on LightTools and Precision Analysis
In order to meet the requirements of observations of the moon as its target by navigation sensors and rendezvous and docking sensor, the moon simulator with large diameter and high irradiation uniformity was designed,the effective irradiation area is Φ2 000 mm. Using LightTools software, the phases, radiance and uniformity of the moon simulator were designed, simulated and analyzed by modeling and tracing method. The phases of the moon and radiance control system was designed to control the 14 typical phases and radiance of the moon in real time. The radiance correction method of the LED array was put forward to improve the uniformity of the simulator. The test results show that the irradiation uniformity of the simulator is better than 15.7% after correction. It indicated that the simulator can be used as the target for sensor identification.
