  • Measurement device employing color appearing due to interference of white light, system, and program
    Patent number: 11274916
    Abstract: A device including: a storage section that stores information for measuring a light path difference of two light paths relating to interference of a white light, from a color appearing due to the interference; and a calculation section that measures, from an image configured by a plurality of pixels each including information representing a color, the light path difference relating to each of the pixels, based on at least the information stored in the storage section.
    Type: Grant
    Filed: July 1, 2020
    Date of Patent: March 15, 2022
    Assignee: MITUTOYO CORPORATION

  • Light source apparatus
    Patent number: 9563001
    Abstract: A light source apparatus includes a light source, an optical fiber, and a positioning mechanism. The positioning mechanism is configured with a planar position adjustment mechanism, an axial line position adjustment mechanism, and an orientation maintaining mechanism. The planar position adjustment mechanism adjusts a position of the optical fiber in a direction following the light-emitting surface. The axial line position adjustment mechanism adjusts the position of the optical fiber in a direction intersecting with the light-emitting surface. The orientation maintaining mechanism holds the optical fiber in a state where an axis direction of the optical fiber lies in a predetermined intersecting direction with respect to the light-emitting surface.
