Multi-channel diffuse light source design

Based on Lambert reflect law, the principal of a novel multi-channel diffuse light source is given. Physical model based on Mont Carlo method simulates the diffuse reflection of light. New-designed mathematical model by coordinate system transforming achieves the tracking of single simulative photon. Simulation of four-channels diffuse light source shows that these light channels are with same optical quality. The four-channels diffuse light source has been applied on reliability testing system, and it assured the comparability of testing result, and saved cost and time greatly.
