Title PHASE OBJECT IDENTIFICATION DEVICE AND METHOD
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 device 1 for identifying a phase object for changing the phase of light includes a light source 2, a sample holding means 3 for holding a phase object 31 to be identified, a holographic recording medium 4 on which a hologram 41 formed by interference between reference light 25 and object light 24 that is phase-modulated by a known phase object 32 is recorded, and a light detector 5, a phase of light 21 emitted from the light source is modulated by the phase object to be identified to generate sample light 22, the hologram of the holographic recording medium is irradiated with the sample light,

reproduced light 23 reproduced from the hologram of the holographic recording medium is detected by the light detector.
