FIELD: digital holography technologies.

SUBSTANCE: invention relates to digital holography technologies and is intended to measure the spatial distribution of the phase delay introduced by the test object into a light wave by forming two interfering light beams from one light beam reflected from the test object or passing through it. The method for registering holographic images of objects consists in the fact that the object under study is illuminated with narrow-band linearly polarized radiation; a light beam is formed from the radiation reflected and scattered by the object under study, which transfers its optical image; using a triangular mirror reflector, this beam is spatially divided into two, one of which is spatially filtered using a pinhole diaphragm; using flat mirrors, the separated beams are directed along identical paths and converge them on a matrix radiation detector; the holographic image formed by the combined beams is recorded by the matrix radiation detector.

EFFECT: ensuring the possibility of adjusting the convergence angle of interfering beams, registration of topographic images of an object in arbitrary narrow spectral intervals, the possibility of recording spectral and spectral interference images of the same area of the object.
