Abstract:
A laser beam (L 50 ) 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 (L 50 ) 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 (L 60 ) on the hologram recording medium ( 45 ) is changed with time. Diffracted light (L 45 ) 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.

Claim (Index 37):
A linear illumination device that projects a line pattern of light onto an object, comprising:\n a coherent light source that generates a coherent light beam, a light beam scanning device that carries out beam scanning by controlling either or both of a direction and a position of the light beam, and an optical diffusing element that diffuses and emits an incident light beam, the light beam scanning device emits the light beam generated by the coherent light source toward the optical diffusing element, and scans the light beam so that an incidence position of the light beam on the light diffusing element changes with time, and the optical diffusing element has a function of forming a linear irradiation region on a nearby surface near the object by diffusing an incident light beam, and is configured so that formed irradiation regions become substantially the same common region on the nearby surface regardless of the incidence position of the light beam.
