摘要
液晶空间光调制器(LCSLM)在非显示领域有着广泛的应用。利用夏克哈特曼波前探测器对LCSLM的相位调制特性进行测量,结果表明,低阶Zernike模式的线性相位调制范围相对较大,随着调制范围的增加,衍射效率下降明显。对LCSLM用于非球面面形测量的可能性进行初步探讨,为扩展非球面面形检测方法提供一种全新的思路。
A liquid crystal spatial light modulator(LCSLM)has a wide range of applications in the non-display field.In this study,the phase modulation characteristics of LCSLM are evaluated using a Shack-Hartmann wavefront detector.The results denote that the linear phase modulation range of the low-order Zernike mode is relatively large,and the diffraction efficiency significantly decreases as the modulation range increases.Furthermore,the possibility of using LCSLM for performing aspherical surface measurements is discussed,which provides a new approach for expanding the method of aspheric surface shape detection.
