Heterodyne Detector/Electronics Design and Alignment of a Pulsed CO2 Laser Wind System,
Abstract
Ten-micron heterodyne laser radar offers a new type of remote sensor that can add significantly to our characterization and understanding of the atmosphere. For example, accurate range-resolved measurements of air velocity via the Doppler of aerosol backscatter--to distances of tens of kilometers--will yield a better understanding of wind shear. This report describes the design of the main TEA laser E-beam modulator and of the electronics systems used for AFC stabilization of the laser frequency, and for matching IR detector outputs to the power and Doppler velocity data channels. Practical details are provided for the alignment of the complex optical system used in this laser wind sensor.
