CONTOURING OF ROUGH SURFACES BY DIGITAL HOLOGRAPHY

Ichirou Yamaguchi

Abstract

Measurement of surface shape of diffusely reflecting objects by phase shifting digital holography is described. After basic principles and an experimental result are briefly explained, a digital simulation algorithm is presented that delivers 2-dimensional distributions of the reconstructed images and contours for general object and hologram recording conditions.

Keywords: digital holography, shape and deformation measurement, speckle suppression
