Abstract:
An optical system for a holographic microscope includes: a light source configured to emit a light beam; a grating configured to split the light beam into a reference beam and an object beam; a lens unit configured to irradiate a sample by the reference and object beams split by the grating; a spatial filter including a first region for the reference beam and a second region for the object beam; and a detector configured to detect an interference pattern caused by the reference and object beams.
