  • Patent number: 8710412
    Abstract: It is possible to generate image data of a biological tissue in a short time. A focus information generating device (2) receives a first reflected light beam (Lr1) split from a reflected light beam (Lr) and a second reflected light beam (Lr2) passing through a pin-hole plate (36). A signal processing unit (13) calculates a uniform reflectance (RE) representing a light amount ratio of the second reflected light beam (Lr2) to the first reflected light beam (Lr1) along with a sum signal (SS) and a difference signal (SD). An integrated control unit (11) detects a position (Z1) corresponding to a top surface (104A) of a cover glass (104) on the basis of the sum signal (SS) and the difference signal (SD) and detects a position (Z3) representing a biological tissue (102) on the basis of the sum signal (SS) and the uniform reflectance (RE).

  • Patent number: 8391112
    Abstract: An optical disk apparatus driving an optical disk includes a tilt-angle adjusting unit configured to adjust a tilt angle indicating the tilt of an optical axis of laser light emitted from a pickup to detect an optimal tilt angle at which a traverse signal has the maximum amplitude and a storing unit configured to store information about the optimal tilt angle. When the optical disk has multiple recording layers on one side, the tilt-angle adjusting unit adjusts the tilt angle with respect to each of the multiple recording layers to detect the optimal tilt angle and the storing unit stores information about the optimal tilt angle with respect to each of the multiple recording layers. The tilt angle with respect to each of the multiple recording layers is controlled in accordance with the information about the optimal tilt angle with respect to each of the multiple recording layers.
