Paper Abstract

Lateral shear between two infrared (10.6μm) beams is produced in a Mach-Zehnder interferometer; these infrared interferograms are recorded on a dynamic recording medium and visualized by means of a reconstruction with a HeNe laser beam. Measurements of the thickness of an Aluminium deposit, the analysis of a Gaussian beam and of an afocal system were performed in real-time.
