We present a general analytical treatment of optical correlation in correlators that use pixellated spatial light modulators with transmissive (or reflective) dead zones in both the input and filter planes. The active areas of the pixels modulate the light intensity while the dead zones transmit (or reflect) all of the light. Our model can predict the changes in the correlation peak and the signal-to-noise ratio with changes in dead zones, calculated in Part I [Appl. Opt. 32, 6527(1993)] from computer simulations. This model is also a general one: It applies to correlators in which one spatial light modulator contaions only opaque dead zones while the other contains only transmissive dead zones; it also applies to the case in which any one spatial light modulator contains both opaque and transmissive dead zones.
我们给出了相关器中光学相关的一般分析处理方法，这些相关器在输入平面和滤波器平面中使用带有透射（或反射）死区的像素化空间光调制器。像素的有源区域调制光强度，而死区透射（或反射）所有光。我们的模型可以预测随着死区变化，相关峰和信噪比的变化，这是在第一部分[《应用光学》32, 6527(1993)]中通过计算机模拟计算得出的。该模型也是通用的：它适用于一个空间光调制器仅包含不透明死区而另一个仅包含透射死区的相关器；它也适用于任何一个空间光调制器同时包含不透明和透射死区的情况。
