Digital Holographic Interferometry of Microdeformations of the Scattering Objects

The principles of holographic interferometry with recording digital holograms and numerical reconstruction procedure of the complex amplitude of the object wave for the calculation of the field displacement surface of the object being discussed. The scheme design and experimental results of the study are presented. 

Methods of Digital Holography in Interference Microscopy of Reflective Object in Partially Coherent Light

The theoretical foundation of the possibility of using the interference microscopes with extended and frequency broadband light source for recording digital holograms of microscopic objects, reconstruction and visualization of phase images is presented. Numerical procedure for processing of spatially localized digital holograms of the focused image in a partially coherent light are considered. Results of experiments on digital holographic microscopy of biological objects in a partially coherent light with Linnik interference microscope are shown.
