An optical receiver was designed and built which, together with pulsed heliumneon lasers being designed and constructed elsewhere, would result in a prototype remote sensing instrument to be used for the detection of natural gas leaks in service lines. The man-portable device, with a range of approximately 15 m (50 ft), will employ the laser differential absorption lidar (DIAL) technique.
