提出了一种用于二维同步检测的新型CCD图像传感器（“锁相成像器”）。测量原理允许每个像素测量振幅调制的大小，相对相位和平均亮度水平（背景）的振荡光波举行，设计，操作和测量结果，这种传感器的一个典型应用将是在3-D成像（距离测量）使用外差干涉。
A new type of CCD image sensor for two-dimensional synchronous detection (''lock-in imager'') is presented. The measurement principle allows each pixel to measure the size of the amplitude modulation, the relative phase and the mean brightness level (background) of an oscillating optical wave held, Design, operation and measurement results are presented, A typical application for this sensor would be in 3-D imaging (range measurement) using heterodyne interferometry.
