摘要： A process by which a multi-image type hologram, wherein one 3D image changes over to another depending on a viewing direction, can be fabricated in a simple construction, and a multi-image type hologram fabricated by that process. According to the process for the fabrication of a multi-image type hologram wherein one image changes over to another depending on a viewing direction, the area of a hologram recording material is divided into a plurality of sub-areas. Objects to be displayed on different images are holographically recorded in the respective sub-areas, using reference light having the same angle of incidence, images recorded in the respective sub-areas are simultaneously reconstructed from the recorded first-stage hologram, so that a second-stage hologram recording material is located near the reconstructed object images for recording them as a reflection or transmission type volume hologram.

摘要： A laser beam is reflected by a light beam scanning device and irradiated onto a hologram recording medium. On the hologram recording medium, an image of a linear scatter body is recorded as a hologram by using reference light that converges on a scanning origin. The light beam scanning device bends the laser beam at the scanning origin and irradiates the laser beam onto the hologram recording medium. At this time, by changing a bending mode of the laser beam with time, an irradiation position of the bent laser beam on the hologram recording medium is changed with time. Diffracted light from the hologram recording medium produces a reproduction image of the linear scatter body on a light receiving surface of the stage. When an object is placed on the light receiving surface, a line pattern is projected by hologram reproduction light, so that the projected image is captured and a three-dimensional shape of the object is measured.
