The determination of a density field by means of digital imaging of a Mach–Zehnder interferogram and processing by a microcomputer is described. The apparatus used in this study are an optical single‐bit digitizer, a microcomputer, and a dot matrix printer. Photographs of the interferograms are semiautomatically digitized by the apparatus. The fringe count and the spatial locations of the fringes are calculated using basic programs, and the density field is plotted as an output.
