Abstract

Interference techniques in digital holography are discussed and experimental results from each technique are presented. Numerical reconstruction algorithms for digital holography are reviewed. The angular spectrum method is seen to be particularly advantageous, with the ability to remove noise and unwanted holographic terms. The dual wavelength optical unwrapping technique offers an unambiguous method of removing 2π phase discontinuity. Application of wavelength-scanning digital interference holography is used to obtain tomographic images with synthesized short coherence length.
