PHASE OBJECT IDENTIFICATION DEVICE AND METHOD

摘要

Provided are a phase object identification device and method capable of identifying a phase object in a method completely different from a conventional phase object observation method or measurement method. A phase object identification device (1) for identifying a phase object for changing the phase of light is provided with 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). The phase object identification device generates sample light (22) by modulating the phase of light (21) emitted from the light source by the phase object to be identified, applies the sample light to the hologram of the holographic recording medium, and detects reproduced light (23) reproduced from the hologram of the holographic recording medium by the light detector.
