A FRESH APPROACH OF PHASE MANAGEMENT TO OBTAIN CUSTOMIZED CONTOURING OF DIFFUSE OBJECT SURFACES OF BROADLY VARYING DEPTHS USING REAL-TIME HOLOGRAPHIC-INTERFEROMETRY

A concept of phase management is introduced in holographic interferometry to obtain customized contouring of diffuse object surfaces. The proposal integrates several useful features: it is non-contact, whole-field, real-time and provides continuously variable sensitivity within a wide range. The method is experimentally shown to be effective for a broad range of object depths. © 1990 Taylor & Francis Group, LLC.
