Abstract

A new imaging interferometer system is described which has been designed with industrial applications in mind. Based on CCD image array detection and Digital signal processing of interferograms in a quadrature optical system, high sensitivity (≈ 1nm) detection of ultrasonic transients and fast data analysis can be achieved. Details of the system are discussed and the results of initial feasibility tests with clean and speckle pattern data presented
