Title: Specific features of partially coherent holography of dynamic objects

Abstract

A method for recording partially coherent holographic interferograms is proposed, which makes it possible to control the sensitivity to the object point displacement by instrumental means. In this case, a decrease in sensitivity is accompanied by a decrease in the depth of the reconstructed image, which simplifies automated inputting of the resulting interferogram into a computer for further processing. The calculations showed that the partially coherent holograms using transverse scale transformation in one of the arms of a recording interferometer with a scale factor different from -1 possess the interferometric sensitivity, whereas the partially coherent holograms with the wave-front rotation in one of the arms of a recording interferometer lack the interferometric sensitivity to the displacement of object points during recording. The latter feature allows us to record objects whose displacement considerably exceeds the wavelength of recording radiation. (laser applications and other topics in quantum electronics)
