Low-power coherent laser radar velocimeter: applications to law enforcement

Abstract
Coherent Laser Radar Velocimetry (CLRV) can provide many advantages to Traffic Monitoring, as compared to traditional microwave systems. Narrower beamwidth, lower transmitted power and higher Doppler frequency shift are some of them. A low-power laboratory, based on the Michelson interferometer, prototype is presented. Experimental results on working range, SNR and resolution are presented.
