Patent number: 11422363Abstract: The present invention is intended to provide an adaptive optics system and an optical device that allow correction of wavefront phase aberration with higher accuracy than before and have a wider correction range than the conventional ones, regardless of the distance between the observation target and the fluctuation layer, and the size of the observation target. An adaptive optics system includes: a wavefront phase modulator that makes aberration correction to incident light and emits the corrected light; and an imaging-conjugated position adjustment mechanism that adjusts freely within a specimen the position of a surface imaging-conjugated with a fluctuation correction surface formed by the wavefront phase modulator. The imaging-conjugated position adjustment mechanism adjusts the fluctuation correction surface to be imaging-conjugated with a fluctuation layer existing in the specimen.Type: GrantFiled: February 22, 2019Date of Patent: August 23, 2022Assignee: INTER-UNIVERSITY RESEARCH INSTITUTE CORPORATION NATIONAL INSTITUTES OF NATURAL SCIENCESInventors: Masayuki Hattori, Yosuke Tamada, Takashi Murata, Yasuhiro Kamei, Mitsuyasu Hasebe, Yutaka Hayano, Shin Oya

Patent number: 7733500Abstract: In a wavefront sensor, an optical wavefront to be measured is split into a first optical path and a second optical path. A wavefront W1 in the first optical path is transmitted through a first compensation member 7, and a wavefront W2 in the second optical path is transmitted through a second compensation member 8. Wavefronts W1 and W2 are mixed together by a semi-transparent mirror 6 with the wavefronts being displaced from each other by a shearing quantity S to form an interference fringe. An optical path difference that occurs between two wavefronts W1? and W2? which reach the interference measurement plane M in a state where the wavefronts are inclined due to the arrival direction of the optical wavefront to be measured is compensated when the wavefronts W1? and W2? are transmitted through the first and second optical path difference compensation members 7 and 8, respectively.Type: GrantFiled: September 16, 2008Date of Patent: June 8, 2010Assignee: National Institutes of Natural SciencesInventors: Jun Nishikawa, Yutaka Hayano

Publication number: 20090161115Abstract: In a wavefront sensor, an optical wavefront to be measured that has entered an entrance pupil P is split into a first optical path L1 and a second optical path L2 by a semi-transparent mirror 3. A wavefront W1 traveling in the first optical path L1 is transmitted through a first optical path difference compensation member 7, and a wavefront W2 traveling in the second optical path L2 is transmitted through a second optical path difference compensation member 8. The wavefronts W1 and W2 are mixed together again by a semi-transparent mirror 6 in a state where the wavefronts are displaced from each other by a shearing quantity S to form an interference fringe on an interference measurement plane M. The intensity distribution of the interference fringe is measured by a photodetector 9, and a configuration of the optical wavefront to be measured is measured by a wavefront measurement portion 10.Type: ApplicationFiled: September 16, 2008Publication date: June 25, 2009Inventors: Jun Nishikawa, Yutaka Hayano

Patent number: 7050204Abstract: An optical reading apparatus and a multifunction-type image forming apparatus, with a minimized thickness in a cabinet height direction and a housing shaped along an upper shape of discharge tray of the image forming apparatus provided thereunder. The optical reading apparatus comprises: platen glass defined with one end and the other end, on an upper surface of which an original document is placed; an optical reading unit that translates between the both ends on a lower surface of the platen glass, for obtaining image data by irradiating an original document surface with light through the platen glass; a control circuit board connected to the optical reading unit, for processing an electric signal; and a housing wherein a side on the side of the other end is thicker than a side on the side of the one end.Type: GrantFiled: November 3, 2000Date of Patent: May 23, 2006Assignees: Nisca Corporation, Toshiba Tec Kabushiki KaishaInventors: Tsutomu Sato, Ryusuke Yamaguchi, Yusuke Hashizume, Kazuyoshi Tsutsumi, Yutaka Hayano, Hiroshi Maejima, Junya Ozawa

Patent number: 6619217Abstract: A decomposition processing apparatus for PCBs prolongs the staying time of the PCBs in a vertical furnace. The apparatus heats and decomposes the PCBs and includes porous staying plates through which the falling PCBs pass, to delay the progress of the PCBs through the apparatus and thus subject the PCBs to sufficient thermolysis.Type: GrantFiled: November 7, 2001Date of Patent: September 16, 2003Inventors: Kanji Kokubu, Yutaka Hayano, Masamitsu Iwasaki
