Experimental Pulsed Laser, Remote Crosswind Measurement System -- Feasibility Study and Design

Abstract

The feasibility determination and design for an experimental, pulsed laser, diffuse target, remote crosswind measurement system is described. The system consists of a laser transmitter, a diffuse target and a receiver. A unique scheme using a double-pulsed, Q-switched ruby laser is used to measure the slope of the time delayed autocovariance function at zero time delay which under appropriate conditions is proportional to the weighted average crosswind along the laser propagation path. The receiver consists of two silicon vidicons, a spinning disk for directing alternate pulses to the vidicons and appropriate scanning circuitry for generating a 10 x 10 array of apertures on each vidicon.
