Abstract

Abstract In a laser radar method for measuring the speed of moving objects, the laser light reflected from the measured object is fed back into the laser resonator and then supplied to a heterodyne receiver. The interaction of the reflected signal with the laser-active medium and the resonator produces an amplification effect which results in a better signal/noise ratio and provides for simpler construction of the measuring device. <IMAGE>
