Abstract:
Provided is a digital holographic imaging apparatus, comprising: an illumination portion (10) having an illumination light emission surface (32i) for emitting coherent light of a specific wavelength as illumination light toward an object (1) side relative to the illumination light emission surface (32i), and a reference light emission surface (32r) for emitting the coherent light, as reference light, in a direction opposite to the illumination light; and an image sensor (50) located on the reference light emission surface (32r) side of the illumination portion (10) and imaging an interference pattern between object light having been modulated by the object (1) and passed through the illumination portion (10) and the reference light of the illumination light, the image sensor (50) having a pixel array (51) comprising two-dimensionally aligned pixels.
