Erbium Laser Rangefinding

Abstract

Laser range finding at 1.54 microns was performed with an erbium laser transmitter and Texas Instruments APD-1.54 germanium avalanche photodetector. Ranging to a 2 x 2 meter target 2635 meters away produced a usable return signal of .7 volt. Trees 3.2 km away yielded return signals of approximately .1 volt. The rangefinder weighed in excess of 50 lb, and would be difficult to adapt to a lightweight system.
