The Design Of Large Solar Simulator Divergent Optical System

The large divergent type solar simulator, Which used in the lunar project subsystem. The sun simulator. Its main role is to test the sun to the interference of rendezvous and docking sensors and used to simulate the sun light after the logo on the lamp to the rendezvous and docking sensors work, Simutaneously simulate aircraft surface objects such as metal skin, docking mechanism glance whether in the sun for rendezvous and docking sensors erro signals, whether to interfere with its normal work.This paper first to deeply investigate the sun simulator, On the basis of the domestic and foreign research present situation and the future development of the investigation and analysis. According to the main research contents and technical indicators to determine its overrall design scheme. And then describes the composition, working principle and the overall structure and layout. Carried out the design of the optical system, using a coaxial transmission divergent systems, and various components of the system were carried out detailed sesign. In order to ensure the effect of concentrated and irradiance, adopting the combination condenser as the condensing system; In order to impro the uniformity of irradiation, using multi-channel optical intergrator is used light-receiving element even. To meet the divergence angle and the irradiated surface diameter requirements, using a condeser lens for collimating the divergent beam divergence and beam diameter at the irradiated surface is controlled. Finally, by lighting software lighttools the system modeling and simulation, and the main technical indicators and test methods for accounting for a simple introduction to verify the correctness of the designed system.
