Abstract

The possibility of using a continuous optical discharge excited by laser radiation as a radiation source in multispectral digital holographic microscopy is investigated. It has been experimentally shown that tunable monochromatization of discharge radiation makes it possible to obtain high-quality digital holograms. Examples of recorded holograms and spatial phase-delay distributions calculated on their basis, introduced by optically transparent samples into the light wave, are presented.
