Spatial light modulators are the key components in real-time optical image-processing systems. The phase and the intensity of their outputs will often depart from ideal behavior. An experimental method is described that permits the effects of multiple distortions, present simultaneously, to be modeled. A computer simulation of a bismuth silicon oxide-based correlator is presented, with spatial light modulators subject to three types of distortion, including phase and amplitude. The experimental method permits both the main effects of the distortions and their interactions to be predicted. Combining all the distortions simultaneously gives a more accurate assessment of the suitability of a spatial light modulator for a given optical processing task. Images of 256 × 256 pixels were used, and the simulation took 15 min. with a Sun SPARCstation 2.
空间光调制器是实时光学图像处理系统中的关键部件。其输出的相位和强度常常会偏离理想状态。本文描述了一种实验方法，该方法可以对同时存在的多种畸变效应进行建模。文中给出了基于氧化铋硅的相关器的计算机模拟，其中空间光调制器存在包括相位和幅度在内的三种畸变类型。该实验方法能够预测畸变的主要效应及其相互作用。同时考虑所有畸变可以更准确地评估空间光调制器对于给定光学处理任务的适用性。使用了256×256像素的图像，在Sun SPARCstation 2上进行模拟耗时15分钟。
