Abstract

We address the problem of single-shot color multiplexed digital holography and propose its new technical realization. To acquire a three-wavelength interference pattern, we propose to implement spectral filtration of wide-band light by means of acousto-optical tunable filter (AOTF) providing three-band operation. We describe digital image processing procedure for amplitude and phase information extraction, and confirm its effectiveness experimentally. Proposed approach may be effective for the detection and classification of structural elements without spectral or mechanical scanning.
