Abstract
An object of the invention is to provide a phase object identification device and method which can identify a phase object in a completely different manner from conventional methods for observing or measuring a phase object. A phase object identification devicefor identifying a phase object for changing the phase of light includes a light source, a sample holding meansfor holding a phase objectto be identified, a holographic recording mediumon which a hologramformed by interference between reference lightand object lightthat is phase-modulated by a known phase objectis recorded, and a light detector, a phase of lightemitted from the light source is modulated by the phase object to be identified to generate sample light, the hologram of the holographic recording medium is irradiated with the sample light, reproduced lightreproduced from the hologram of the holographic recording medium is detected by the light detector.
