An Application of Holography to Interference Microscopy

Abstract

An experimental two-beam interference microscope has been constructed which uses a hologram to generate one of the beams. This eliminates the need for selecting matched optics as required in conventional systems. Using the techniques described in this paper, one can modify a conventional bright field microscope to produce horizontal and oblique section interferograms in real or recorded time, or differential and totally doubled interferograms in real or recorded time. The optical configuration of the microscope is explained, and experimental results are given for the transmitted light case.
