Bessel fringes modulation determination by directional spatial carrier phase shifting

Adam Styk , Helena Dziubecka

Abstract

Time averaging technique applied to different interferometric methods is one of the most commonly used measurement technique in vibration testing. The information on amplitude of vibration is encoded in so called fringe envelope function described by the J0 Bessel function in case of harmonic motion. In the presented paper the author proposes novel solution for amplitude distribution evaluation. It is based on the analysis of the Bessel pattern modulation distribution. For modulation evaluation and Directional Spatial Carrier Phase Shifting (DSCPS) method are used. Conducted error analysis prove usefulness of the proposed approach.
