Acoustooptic Spectrum Analysis and Narrowband Interference Excision in Wideband Signal Environments.

Abstract

This thesis is a study of performance measures for acoustooptic spectrum analysis, and optical excision of narrowband interference. A Gaussian laser beam model is developed and programmed for propagation through thin lenses. Effects of beam truncation by Bragg cell apertures are examined. Bragg cell performance is analyzed with respect to diffraction efficiency, information capacity, and response agility. A performance comparison is made between charge-coupled device and photodiode technologies in photodetector array applications. Overall excisor performance is discussed in terms of interference removal effectiveness and process corruption of residual information bearing signals. (Author)
