Patent number: 10948878Abstract: An optical device including a hologram recording medium that can reproduce an image of a reference member and an irradiation unit that emits a coherent light beam to the optical device. The irradiation unit includes a light source for emitting a coherent light beam and a scanning device capable of adjusting a reflection angle of the coherent light beam emitted from the light source and that makes a reflected coherent light beam scan the hologram recording medium. The light source has light sources for emitting coherent light beams having different wavelength ranges. The hologram recording medium has a plurality of recording areas to be scanned with a plurality of coherent light beams reflected by the scanning device, respectively. Each of the plurality of recording areas has an interference fringe that diffracts a coherent light beam of the corresponding wavelength range.Type: GrantFiled: October 24, 2018Date of Patent: March 16, 2021Assignee: Dai Nippon Printing Co., Ltd.Inventors: Makio Kurashige, Kazutoshi Ishida, Tomoe Takanokura, Yasuyuki Ooyagi

Patent number: 10523902Abstract: 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.Type: GrantFiled: June 28, 2018Date of Patent: December 31, 2019Assignee: DAI NIPPON PRINTING CO., LTD.Inventors: Makio Kurashige, Kazutoshi Ishida, Tomoe Takanokura, Yasuyuki Oyagi
