Observe Phase Body by Improving Lightly-Off-Axis Interferometry under Optical Microscopy

Abstract:

Recently, the phase microscopy imaging (PMI) got more and more application in phase body observing. In this article, we put out one off-axis interferometry adding method utilizing amplification of optical microscope (OM), in which, one device was designed by improving Mach-Zehnder optical structure in order to suit with the structure of OM. A wrapped phase image could be got by this system base on Hilbert off-axis interferometry method. The experimental results of samples (one glass grating and polystyrene micro particle) show that unwrapping images retrieval the shape and structure of phase bodies and the system works well. The improved optical microscope system can observe both opacity specimens and translucent specimens.
