Analysis of Focused Laser Differential Interferometry [PDF]
31st AIAA Aerodynamic Measurement Technology and Ground Testing Conference, 2015 A computational method for predicting the output of a focused laser differential interferometer (FLDI) given an arbitrary density field is presented. The method is verified 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
