The paper describes a method of measuring small, rapidly changing fringe displacements of a Mach-Zehnder interferometer by combining the interferometer with a time resolving monochromator and isolating a small region of the fringe field. The application of the technique to ionization relaxation studies and hot flow duration measurements in shock tubes is indicated.
