本文提出了一种将入射光与电子信号的相关检测器集成为二维阵列的新型图像传感器。该结构的特点是：1)光电二极管用于将入射光子转换为电流（乘法器），2)一个或几个所有像素共有的外部电信号（乘法器），3)光电电流和外部信号的乘法器，4)电容器用于积累乘积作为相关结果，5)CCD或MOS开关网络用于扫描出相关结果。介绍了该传感器的几种设计和应用。
This paper proposes a new type of image sensor on which correlation detectors between incident lights and electronic signals are integrated as a 2-D array. This architecture is characterized by: 1) photodiodes for converting incident photons to currents (multiplicands), 2) one or a few external electric signals (multipliers) which are common to all pixels, 3) multipliers of the photo currents and the external signals, 4) capacitors for accumulating the products as the correlation results, and 5) CCD or MOS switching networks for scanning out the correlation results. Several design and applications of the sensor are demonstrated.
