Paper Abstract

A simple method of generating pseudo Fizeau fringes on large objects with deformations of the order of a few centimeters is described and demonstrated. A stereo pair of photographs of the object are placed one in each arm of a Mach-Zehnder interferometer and are then imaged onto a common image plane. A knife edge placed in the back focal plane of the imaging lens deforms the straight line fringes of the Mach-Zehnder interferometer to provide relief information of the object. The functional form of the deformed fringes is shown to be equivalent to Fizeau fringes.
