    Abstract: With a simple configuration, a clear illumination area with suppressed blurring is formed, and a form such as position, shape, and size thereof is changed. Divergent light (L110) from a point light source (110) is shaped by a collimating optical system (120) and emitted to a hologram element (130). Since the point light source (110) is arranged at a front focal position of the collimating, optical system (120), the light (L120) emitted from the collimating optical system (120) is emitted to the hologram element (130) as parallel light, and diffracted light (L130) therefrom forms an illumination area (150) at a predetermined position on an illumination target surface. A light scanning part (140) rotating about a predetermined rotation axis (r) is arranged between the point light source (110) and the collimating optical system (120), and light (L140) incident on the collimating optical system (120) is scanned. By this scanning, an incident angle of the parallel light (L120) incident on the hologram element (130) changes, and a form of the illumination area (150) changes.

    Abstract: 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.
