| 摘 要： | 利用实测影响函数，通过数值仿真分析了有效孔径、光束入射角度对于20单元双压电片变形镜像差校正能力的影响。仿真结果表明:有效孔径为16 mm时，变形镜对于各阶像差的校正能力较好；而随着光束入射到变形镜角度的增大，变形镜对于像差的校正精度与校正幅度都会出现下降，但是如果能够将入射角控制在25以内，入射角度对变形镜的像差校正能力影响不大。

| Abstract: | The impacts of effective aperture size and beam incident angle on the aberration correction ability of a 20-actuator bimorph deformable mirror whose clear aperture is 30 mm are numerically analyzed based on measured influence functions. Numerical simulations show that, when the effective aperture is 16 mm, the deformable mirror can correct aberrations well. The increase in the beam incident angle lowers both the correction accuracy and amplitude. However, if the incident angle is limited within 25°, the impact of beam incident angle is not obvious. |
