摘要
基于Ｚａｒｎｉｋｅ多项式的概念，提出了三自由度模式变形反射镜激光谐振腔象差的自适应校正原理，分析了系统开环传递函数和系统稳定性。闭环系统计算机模拟结果表明，该系统在频率为１０Ｈｚ以下的外界相位扰动的情况下。
Based on the Zernike polynomials,this paper presents an adaptive correction theory of laser resonator phase aberrations by using a modal deformable mirror with 3 freedoms.The open loop transfer function and the system stability are analyzed.The results of the close loop computer simulation show that this system can compensate the dynamic phase aberration up to 90% for the phase disturbances within the frequency range of 0￣10Hz.
