Paper Abstract

A new type of laser radar system with off-axis parabolic rotating surfaces and a hyperbolic plane-convex lens configuration is designed in this paper. Three dimensional vector theory of reflection and refraction are utilized to design and analyze the structural parameters of the system. Ray tracing simulation are performed and results show that the new system can greatly decrease energy loss which is caused by central reflection from the secondary reflector in cassegrain-type antenna. In ideal conditions, the divergence angle of the transmitting rays can be compressed to 0.04 mrad. The incident lights will converge to the fiber core if the incident angle is less than 0.65 μmad. This design provides a practical way to improve performance of laser radar system.
