Abstract:
1. A digital holography device comprising: a light source to emit light, the light source being provided for supply of an object light beam formed by at least one of radiation, transmission, scattering, reflection, and diffraction from a subject according to the emitted light; a phase-shifting element to split the light emitted from the light source into two kinds of reference light beams having different phases in a plane perpendicular to a direction in which the light emitted from the light source travels; image-capturing device including an image-capturing plane on which two kinds of interference fringe patterns are recorded, the interference fringe patterns being formed by interferences between the two kinds of reference light beams and the object light beam; and an image reconstruction device to generate a reconstructed image of the subject according to the two kinds of interference fringe patterns recorded on the image-capturing plane and intensity distribution of the reference light beams, wherein intensities of the reference light beams are higher than an intensity of the object light beam.
