Pulsed GaAs laser terrain profiler.

A pulsed GaAs laser terrain profiler has been successfully tested and flown. Preliminary flight data indicate excellent resolution, with terrain features easily identifiable. Unique design features and typical flight results are given. The laser profiler is to be used as part of an airborne surveying package which will contain an inertial measurement unit and laser tracker to provide three-coordinate position information as well as base motion isolation and stabilization control for the profiler.
