LASER WAVEFRONT ANALYZER USING FREQUENCY OFFSET INTERFEROHETRY

摘要

The Laser Wavefront Analyzer has as its primary goal the measurement of the spatial distribution of the phase and intensity of a high power (9.2 to 10.7 micrometers) laser wavefront at high framing rates. The objectives of this study were: (1) to arrive at a preliminary baseline design for a Laser Wavefront Analyzer that would meet as many of the original design goals as possible, and (2) to investigate the cost/complexity savings that could be achieved by relaxing some of the performance specifications of the baseline design. The baseline design for the Laser Wavefront Analyzer consists of four major subsystems. These are the Beam Sampler Subsystem, the Autoalignment Subsystem, the Optical Subsystem, and the Data Acquisition Subsystem.
