Zusammenfassung:PROBLEM TO BE SOLVED: To provide a device for forming a coherent three-dimensional wave front by using many off-axis incoherent/coherent converters and an image optical system by combining the device for forming a synthetic wave front synthesized from a set of sectional images for which parallax vertical to the axis of the parallax is removed or the like. SOLUTION: This device is composed by combining the device for forming the synthetic wave front synthesized from a set of the sectional images for which the parallax vertical to the axis of the parallax is removed, the device for controlling the irradiation parameter of an optical system and removing the parallax and the device for calculating a white light re-synthesis frequency for various reproduction shapes, etc. In the device, a set of the images of an off-axis area are formed for the images arranged in different distances along an optical axis by an image connecting device like a hologram. The images are obtained from the off-axis incoherent/coherent converters 8a-8f like liquid crystal light emitted by a laser.
