Publication number: 20210341288Abstract: [Object] To provide an interferometric optical fiber gyroscope that can perform higher-accuracy measurement and can be produced at a low cost. [Solving Means] An interferometric optical fiber gyroscope is an interferometric optical fiber gyroscope that detects angular velocity by optical interference between counterclockwise light and clockwise light. In such an interferometric optical fiber gyroscope that detects angular velocity by optical interference between counterclockwise light and clockwise light, the interferometric optical fiber gyroscope includes: a sensing coil mechanism including a multicore fiber that includes a plurality of transmission cores, and a multicore fiber optical path junction that optically couples at least a first transmission core and a second transmission core, of the plurality of transmission cores.Type: ApplicationFiled: July 17, 2019Publication date: November 4, 2021Inventors: Shinji MITANI, Kenichiro NIGO, Tadahito MIZUTANI, Satoshi KARASAWA, Yusaku TOTTORI, Taketoshi TAKAHATA, Haruyuki ENDO, Yuichi TAKUSHIMA, Shigeru NAKAMURA

Patent number: 8588564Abstract: A confocal optical system comprising a scanning fiber is provided. The scanning fiber is a single-mode fiber of which a first end is shaped as a curved surface. The scanning fiber transmits illumination light to the first end. The illumination light is emitted toward an observation area. The illumination light emanates from the first end. The illumination light emanates from the first end striking a target area within the observation area. The first end receives at least one of reflected light and fluorescence from the target area. The reflected light is the illumination light reflected from the target area. The fluorescence is induced at the target area by illumination from the illumination light.Type: GrantFiled: May 10, 2010Date of Patent: November 19, 2013Assignee: Hoya CorporationInventor: Satoshi Karasawa

Patent number: 8420781Abstract: An object of the present invention is to provide a red or orange fluorescent protein, which is characterized in that the difference (stokes shift) between an excitation peak value (wavelength of maximum absorption) and a fluorescence peak value (wavelength of maximum fluorescence) is greatened, so that the maximum fluorescence can be obtained by the maximum excitation. The present invention provides a novel fluorescent protein monomerized by introducing a mutation into a florescent protein derived from Fungia sp., and a novel chromoprotein and fluorescent protein derived from Montipora. sp.Type: GrantFiled: August 2, 2011Date of Patent: April 16, 2013Assignees: Riken, Medical & Biological Laboratories Co., Ltd.Inventors: Atsushi Miyawaki, Takako Kogure, Hiroshi Hama, Masataka Kinjo, Kenta Saito, Satoshi Karasawa, Toshio Araki
