  • Patent number: 11469820
    Abstract: An adaptive optical apparatus includes a first deformable mirror that includes a reflecting surface reflecting light propagated through an atmosphere, and a drive unit having a plurality of drive elements and changing an uneven shape of the reflecting surface, a second deformable mirror that includes a reflecting surface reflecting the light from the first deformable mirror and a drive unit having a plurality of drive elements and changing an uneven shape of the reflecting surface, a detector that detects light intensity of the light from the first deformable mirror and the second deformable mirror, and a controller that controls the drive unit of each of the first deformable mirror and the second deformable mirror. The controller is configured to execute a first update operation of controlling the drive unit of one deformable mirror based on a detected value by the detector.

  • Patent number: 11092800
    Abstract: An adaptive optical apparatus includes a first deformable mirror that includes a reflecting surface reflecting light having propagated through an atmosphere, and a drive having a plurality of drive elements and changing an uneven shape of the reflecting surface. There is also a second deformable mirror that includes a reflecting surface reflecting the light from the first deformable mirror and a drive unit having a plurality of drive elements and changing an uneven shape of the reflecting surface. There is also an optical path splitting unit that splits the light from the second deformable mirror into a first optical path and a second optical path, a first sub-deformable mirror in the first optical path that includes a reflecting surface and a drive unit that correspond to the reflecting surface and the drive unit of the first deformable mirror, and a second sub-deformable mirror.

  • Patent number: 7582057
    Abstract: Endoscopic system 40 comprises composite optical fiber 34 that consists of a large-diameter, laser light transmitting optical fiber surrounded by a large number of image transmitting fibers that are bundled together to form an integral assembly with the central fiber, laser applying and image observing optical unit 42 that is connected to the eyepiece portion of said composite optical fiber such that it launches laser light into said large-diameter optical fiber and that the image being transmitted through said image transmitting optical fiber is focused on a camera to become observable, and an illuminating light transmitting unit that transmits illuminating light to the tip of the objective portion of said composite optical fiber for irradiation purposes.
