Abstract


Low-light level night vision device testing equipment is used to detect stability of low-light level night vision device and performance indicators, and the low-light level stress source system provide night lighting environment. This thesis mainly described the design principle and the implementation of electrical part of the low-light level stress source system.Firstly, This thesis mainly described the main structure of low-light level stress source system-integrating sphere. Then,it introduced principles light source control system drive and control circuits, illumination switching control systems and light detection system of each low-light level stress source system. Then, used Monte Carlo method simulated the light within the integrating sphere with MATLAB, it also texts the theoretical feasibility of designed low-light level stress source system. Finally, this paper detects the performance indicators of the system in the actual operation, and texts the work of low-light level stress source system.Low-light level stress source system described in this article can effectively improve the stability of the light source and control reliability, and it achieves remote automatic control for low-light level stress source system, it agrees with the test standard for testing night vision device.
