    摘要: A laser beam (L50) is reflected by a light beam scanning device (60) and irradiated onto a hologram recording medium (45). On the hologram recording medium (45), an image (35) of a linear scatter body is recorded as a hologram by using reference light that converges on a scanning origin (B). The light beam scanning device (60) bends the laser beam (L50) at the scanning origin (B) and irradiates the laser beam onto the hologram recording medium (45). At this time, by changing a bending mode of the laser beam with time, an irradiation position of the bent laser beam (L60) on the hologram recording medium (45) is changed with time. Diffracted light (L45) from the hologram recording medium (45) produces a reproduction image (35) of the linear scatter body on a light receiving surface (R) of the stage 210. When an object is placed on the light receiving surface (R), 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.

    摘要: A method for producing a hologram recording an interference fringe formed by an object light and a reference light on a photosensitive dry plate, and the object light either having diffusing and scattering characteristics or being passed through an optical diffusion body, mainly includes the following steps: In a first step, a ratio η RO /η OO of a first diffraction efficiency η OO and a second diffraction efficiency η RO , is calculated. The diffraction efficiency η OO is dependent on two object light beams. The efficiency η RO is dependent on the object light and the reference light. In a second step, the intensity E O of the object light and the intensity E R of the reference light is adjusted in such a way that the ratio η RO /η OO is set to at least 10 and the efficiency η OO does not exceed 5%.
    A display device using the above hologram is structured by a display unit for generating a signal light; a hologram screen formed by either reflection or transmission hologram, and a projecting unit for projecting the signal light to the hologram screen.
    According to the present invention, it is possible to easily produce a hologram, for example, a screen hologram, having no cloudiness or cloudy state when an observer observes an image displayed on the screen, and to a display device using the above hologram screen.
