Abstract

Aspheric surfaces are widely used in optical systems. Advanced testing technology is needed for the production of aspheric surfaces. Compensation method is a popular method for testing aspheric surfaces. In order to realize the certification of compensator that is composed of multiple lenses, reflective CGH whose diameter is smaller than that of aspheric surface is used as aspherical simulator to calibrate the compensator. The challenge of realizing the accurate certification of the compensator is of high accuracy design of CGH. According to optical propagation theory, wavefront tracing method is proposed in this dissertation. The derivation process of wavefront tracing method is given. By using this method, the phase function of CGH can be directly acquired. Simulators of many different aspheric surfaces are designed. The design results prove the feasibility of wavefront tracing method. Compared to ray tracing method, the wavefront tracing method can simplify the design process and improve the design accuracy.
