Analysis of Focused Laser Differential Interferometry
A computational method for predicting the output of a focused laser differential inter-ferometer (FLDI) given all arbitrary density field is presented. The method is validated against analytical predictions and experimental data. The FLDI simulation software is applied to the problem of measuring Mack-mode wave packets in a hypervelocity boundary layer on a 5° half-angle cone. The software is shown to compliment experiments by providing the necessary information to allow quantitative density fluctuation magnitudes to be extracted from experimental measurements.
