Optical Microtomography of Phase Objects

摘要

The method of computer tomography is proposed to be used for the reconstruction of the spatial distribution of the refractive index of optically transparent (phase) microobjects. A Mach-Zehnder interferometer with a microscope of the transmission type in the object channel is used for the formation and visualization of projection data. The phase step method is used for automated decoding of interferograms. Interference projections are obtained and a transverse tomogram of an individual erythrocyte of a sample of human blood is reconstructed.
