Paper Abstract

A prototype of a homodyne laser radar system for surface displacement monitoring using the reference beam technique is presented. The prototype is very simple, is easy to align and focus, and is able to measure the velocity of the surface displacement at distances up to 16 m. We present an optical analysis of the prototype, a power budget, a criterion on tolerance in distance and laboratory measurements.
