Abstract
A prototype of a homodyne laser radar system for surface displacement monit oring using the reference beam technique is presented. The prototype is ver y simple, is easy to align and focus, and is able to measure the velocity o f the surface displacement at distances up to 16 m. We present an optical a nalysis of the prototype, a power budget, a criterion on tolerance in dista nce and laboratory measurements. (C) 2001 Society of Photo-Optical Instrume ntation Engineers.
