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.
