| 摘 要： | 基于几何光学理论利用光线追迹方法得到了适用于任意面型相位板的大视场平行光入射情况下的光线像差近似表达式,并在此基础之上分析了奇对称型相位板波前编码系统的点列图的大小、边界以及光线结构等特性,研究了大视场角平行光入射下的光线像差增强及点列图形变等现象,并且给出了相应的近似数学解析式来描述这些特性。通过对奇对称型相位板波前编码成像系统的点列图特性分析,有助于进一步的理解波前编码技术并且指导实际系统的设计。

| Abstract: | The ray tracing method in geometric optics is applied to acquire the asymptotic expressions of ray aberrations for phase plates of free form illuminated by collimated beams with large field of view,with which the spot diagram characteristics of the wavefront coding imaging system with anti-symmetric phase plates,including spot size,boundaries,and ray intersection structures,and ray aberrations enhancements and spot shape variations due to the large view-field angle are analyzed.The corresponding asymptotic expressions to describe the above characteristics are presented.With this spot diagram characteristics analysis,a deeper insight into the wavefront coding imaging systems is acquired and instructions for designing real systems are found. |
