Patent number: 10724845Abstract: The optical module for optical height measurement includes a laser light source, an irradiation optical system, a detection optical system, and a detector. The laser light source is configured to irradiate the layer-structured specimen with a light beam. The irradiation optical system includes an objective lens. The objective lens is located to be approximately perpendicular to the layer-structured specimen. The detection optical system is configured to guide a reflected light reflected by the layer-structured specimen and a light passing through the objective lens and an aperture-restrictor-for-return to the detector. The aperture-restrictor-for-return is located immediately after the objective lens. The aperture-restrictor-for-return is configured to restrict the reflected light and cause only a light in a high NA region to pass through. The detector is configured to convert an entered light into a light detection signal. The detector includes a multi-divided detector array.Type: GrantFiled: October 24, 2018Date of Patent: July 28, 2020Assignee: HITACHI-LG DATA STORAGE, INC.Inventors: Daisuke Tomita, Hideo Suenaga, Takahiro Kurokawa, Yoshitaka Morimoto

Patent number: 9778077Abstract: It is made possible to amplify signal light of an optical fiber sensor and to perform measurement in a long distance. At least one of a plurality of core wires in a multicore optical fiber is used as a signal-light propagating core wire 133 and the other is used as a reference-light propagating core wire 134. Also, homodyne detection of signal light and reference light reflected by an FBG sensor unit 132 arranged in each measurement point is performed. Thus, signal light is amplified. In order to make a difference between optical path lengths of the signal light and the reference light equal to or smaller than a coherence length, an optical path-length adjustment unit including a piezoelectric element or the like is arranged in an optical path of the reference light.Type: GrantFiled: February 28, 2014Date of Patent: October 3, 2017Assignee: Hitachi, Ltd.Inventors: Yoshitaka Morimoto, Takahiro Kurokawa, Koichi Watanabe

Patent number: 9293168Abstract: When data is recorded on an optical disc, and stored for a long period of time, there is a need to periodically evaluate whether a quality of the recorded data is determined with time, or not. If the signal quality is lower than a given level as an evaluation result, a work for moving the data to a brand-new optical disc is required. However, in periodical inspection, if the number of optical discs is enormous, a large amount of time is required to evaluate all data recorded on the optical disc. In recording user data on the optical disc, a signal of a particular pattern having a lifetime shorter than a reference lifetime of the user data is recorded in a given area of the optical disc in advance, the particular pattern signal is reading at given time intervals, and processing on the user data is determined on the basis of the evaluation result of the signal quality.Type: GrantFiled: January 29, 2014Date of Patent: March 22, 2016Assignees: HITACHI CONSUMER ELECTRONICS CO., LTD., HITACHI—LG DATA STORAGE, INC.Inventors: Yoshitaka Morimoto, Soichiro Eto, Koichi Watanabe
