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.
