Abstract

We composed optical system which is made of two optical lenses, beam expander, and Laser Diode(LD). When the light from the LD pointed to the remote moving object, we optically aligned to achieve full power performance in the given angle range. We also reviewed optical design data with Light Tools, and measured some factors including LD cell, surface roughness and refringence. The result shows that the laser point source optical system displayed good uniform power shape, and the LD used for this experiment to be guaranteed superior output power performance compared to conventional specifications.
