Abstract
Using a modified Michelson interferometer configuration, the flatness of micro mirror cell surface was probed. Interferograms were captured at CCD camera plane by defocusing object beam onto the micro mirror with microscope objective lens. And these were compared with the interferograms made with the flat metallic mirror. Also, the theoretical analysis is presented.
