Title: Optical homodyne microscope

Abstract: An optical homodyne microscope is disclosed which detects phase modulation of the optical radiation that is reflected from an object under study which is in a state of periodic motion. The dimensions of the object may be smaller than the optical wavelength with this technique. By analyzing the resultant phase modulation spectrum, information concerning the shape of the object can be obtained.
