    摘要： DIGITAL HOLOGRAPHY DEVICE AND PHASE PLATE ARRAY
    Provided is a digital holography device (1) having a simple configuration and an improved image quality, including: a light source (4) that emits light, the light source being provided for supply of object light beams formed by radiation, transmission, scattering, reflection, or diffraction of the emitted light from a subject (6); an array device (2) that splits the light emitted from the light source (4) 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 (4) travels; a CCD camera (3) having an image-capturing plane (13) 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, which have been produced by the array device (2), and the object light beams, which have been formed by radiation, transmission, scattering, reflection, or diffraction from the subject (6); and an image reconstruction device that generates a reconstructed image of the subject (6) from the two kinds of interference fringe patterns recorded on the image-capturing plane (13).
