Multiplex coding of optical images is discussed for photon-counting operation in both the signal- and dark-count-dominated domains. Both intensity measurement and signal detection are discussed. The advantage of multiplex operation in both situations is demonstrated and comparison made with alternative imaging techniques. The effects of code noise, detector area, response time, and dynamic range are discussed. It is shown that in dark-count-dominated operation, e.g., ir imaging applications, the limiting factor on multiplex gain is the light collection following image coding. Higher bandwidth detection is also required: for instance, a typical ir detector transmitting a 100 x 100 element image with individual element resolution of 2(5) will need a total dynamic range of 2(12) and an exponential response time a factor of 2.4 faster than for a single detector.
本文讨论了在信号计数和暗计数主导的领域中，用于光子计数操作的光学图像复用编码。同时讨论了强度测量和信号检测。论证了在这两种情况下复用操作的优势，并与其他成像技术进行了比较。讨论了编码噪声、探测器面积、响应时间和动态范围的影响。结果表明，在暗计数主导的操作中，例如红外成像应用，复用增益的限制因素是图像编码后的光收集。还需要更高带宽的检测：例如，一个典型的红外探测器传输一个100×100像素的图像，单个像素分辨率为2(5)，则总共需要2(12)的动态范围，且指数响应时间比单个探测器快2.4倍。
