Abstract
A dual shaped reflector system based on kinematic and dynamic ray tracing technique is developed to achieve a circular, collimated, and uniform beam from an elliptical Gaussian beam generated by the Quantum Cascade Laser(QCL) applied in terahertz holographic image system. Simulation result shows that the system has achieved ±0.7dB amplitude ripple and ±7 degree phase vibration for the output beam profile.
