PURPOSE:To obtain a color hologram information signal by making a light beam obtained from a substance receiving the irradiation of incohereant light incident upon a circulation type interference optical means and receiving interference light radiated from the optical means to a scanning type image pickup part. CONSTITUTION:Circulating optical paths 17Rm, 17G and 17B and output optical paths extended from respective optical paths form the circulation type interference optical means as a whole. Red, green and blue hologram information signals SHr, SHg, SHb are resepectively obtained from image pickup signal processing parts 27R, 27G, 27B receiving scanning outputs from the image pickup parts 25R, 25G, 25B receiving interference light beams IRi, LGi, LBi from the optical means. These signals are supplied to respective BPFs 28R, 28G, 28B, thereby a background noise is reduced and the noise-reduced signals are outputted to output terminals 29R, 29G, 29B.
