DIGITAL HOLOGRAPHY APPARATUS AND DIGITAL HOLOGRAPHY METHOD

摘要

　Image components of a desired wavelength are extractably recorded or played back. A digital holography apparatus (1) according to an embodiment of the present invention is provided with a monochrome image-capture device (12) for capturing an image of a hologram formed by interference between reference light having a wavelength ofλ1/λ2 and object light. The image-capture device (12) captures an image of a first through third hologram each having a different phase shift amount for wavelengthλ2 only, and of a fourth hologram having a different phase shift amount from the first hologram for wavelengthλ1 only.
