Design, alignment, and calibration of a focused laser differential interferometer
Mallory C. Neet, Joel M. Lawson, Joanna M. Austin
Abstract
Methods are presented for systematic selection of optical components and dimensions for the design of both single- and double-focused laser differential interferometers (FLDIs). Step-by-step instructions for the assembly and alignment of each FLDI component are given, including detailed figures of the interferometer fringe behavior, as the required infinite-fringe configuration is approached. Calibration and data post-processing techniques are provided in order to obtain quantitative signals from the FLDI.
