Abstract
Laser light pulses are reflected off a scanning mirror. A time-of-flight distance measurement device receives reflected light pulses and determines distances. The light pulses have abrupt changes in amplitude. Reflected pulses are differentiated to reduce sensitivity to amplitude variations. Differentiated pulses may be compressed to keep the receiver from saturating. Distance measurements are combined with location information to produce a 3D image of a surface.
