摘要

液晶调制器件的相位分布一直无法实现精确的区域表征，同时相位分布曲面的驱动电场也只能通过间接光学调制结果进行调整，因此我们构建了一种相位分布曲面的自适应调制系统。通过将相位深度转换为透过率，并经过高分辨率探测器件的灰度测试，可以得到精确的区域相位深度信息。系统将实际的相对透过率分布曲面与预期中理想的相对透过率分布曲面做比较，代入自适应算法得到新的电压信号，形成自动化的闭环控制环路。针对迭代调试复杂的问题，通过自适应调制系统大大减少相位调制过程中的时间，提升相位分布的调制精度。可广泛应用于液晶光栅和液晶透镜等电控相位调制器件。

Abstract

The phase distribution of the liquid crystal modulation device is unable to achieve accurate regional characterization

and the driving electric field of the phase distribution can only be adjusted by the indirect optical modulation result. Therefore

we constructed an adaptive modulation system of the phase distribution. By converting the phase depth to transmittance and passing the gray scale test of the high-resolution detector

the accurate regional phase depth information can be obtained. The system compares the actual relative transmittance distribution with the expected ideal relative transmittance distribution and substitutes the adaptive algorithm to obtain a new voltage signal

forming an automated closed-loop control loop. Aiming at the complicated problem of iterative debugging

the adaptive modulation system greatly reduces the time in the phase modulation process and improves the modulation accuracy of the phase profile. It can be widely used in phase modulation devices such as liquid crystal gratings and liquid crystal lenses.
