Abstract

The camera includes two functionally equivalent line and field scanners, one for issuing a light pulse that will be returned by an object point, and identified by a particular line/field scanning position in both scanners; the second scanner being attuned to recognize the returned light in one scanning raster point only for purposes of correlation. The field scan is realized through a deflecting mirror or in a columnal array the line scans are either solid state or fiber optics.
