1. A device for pixel correlating a passive spectral image with a lidar range image, comprising: (a) an electro-optical focal plane array for receiving light at a first given time that has been reflected from a first location, and producing image data signals therefrom; (b) a lidar transceiver means for transmitting a first beam of light and receiving back-scattered light at a first given time that originated from said beam and has been reflected back from the first location, and producing distance data signals from said back-scattered light; and (c) a means for electronically synchronizing a process of receiving the image data signals corresponding to the first location and the distance data signals corresponding to said first location, to thereby register the image data signal from the first location at the first given time at a first pixel and register the distance data signal from the first location at the first given time for a first beam of light.
