Abstract

We describe results from an optical detector capable of producing three-dimensional images using single laser pulses. The method consists of detecting reflected light from an object illuminated by a short pulse from a laser with a detector that resolves many pixels in the object's image into fine time bins equivalent to range resolution of 4 cm. The detector utilizes a fiber optic image converter to transform a square focal plane into a line array that is input to a streak camera to obtain high time resolution in all the pixels. We show data from simple objects, like posts and cones, as well as more complicated objects. This work builds upon our results reported in September 1988 at the Laser Radar III SPIE conference. In that work we imaged the entire object to a point that was a single input to the streak camera. In addition we viewed the object from many aspect angles and used the range measurements to produce a two-dimensional projection image of the object. That method of reflective tomography requires gathering data from many aspect angles while the method reported here, which we call angle-angle-range, provides a three-dimensional image with data from a single aspect angle using a single laser pulse. Here we will compare the methods in detail.
