摘要
The invention provides an optical tracing system for measuring elevation of a reference body above a reference surface, comprising a laser transmitter radiating a light beam in a downward direction; an optical unit for imaging the radiation reflected from said body and said surface on a detector; filtering means for separating light originating from said laser from background illumination, and signal processing means for identifying said reference body and for measuring the elevation thereof from said surface.
