    Abstract: Provided is a holographic microscope including an input optical system configured to emit polarized input beam, a first beam splitter configured to emit an object beam by reflecting a portion of the polarized input beam, and emit a reference beam by transmitting a remaining portion of the polarized input beam, a reference optical system configured to separate the reference beam into a first reference beam and a second reference beam, a camera configured to receive the first reference beam and the second reference beam and the object beam that is reflected by an inspection object, the camera including a micro polarizer array, wherein a first polarization axis of the first reference beam is perpendicular to a second polarization axis of the second reference beam.
