PROBLEM TO BE SOLVED: To provide a hologram imaging device in which optical path configuration is simplified and its adjustment and setting are easy. SOLUTION: An optical laminate Osp as a light dividing and projecting means obtained by laminating a reflective polarizing plate 3 and aλ/2 retardation plate 4 is located on the sensor array side of a photosensor array plate Aps obtained by carrying out matrix arrangement of a plurality of photosensors 2 on a transparent glass substrate 1 by way of a transparent insulating layer, and a semiconductor laser 5 as a light source and a light source section Ls in which light emitted from the semiconductor laser 5 is guided and made incident on the glass substrate 1 of the photosensor array plate Aps in the form of a parallel luminous flux are located on the opposite side. Emitted light from the semiconductor laser 5 is passed through the photosensor array plate Aps and divided into reflected light and transmitted light by the optical laminate Osp, the reflected light is projected as reference light on the corresponding photosensor, the transmitted light is converted to object light by reflection on a limbless wooden doll f as an object to be imaged, and the object light is made incident again and made outgoing toward the same photosensor 2.
