  • Publication number: 20230417662
    Abstract: One mode of an optical inspection apparatus according to the present invention is an optical inspection apparatus for optically inspecting an object, the optical inspection apparatus including: a biasing section (20) configured to apply, to a group of objects (23A) on a stage, a force for moving the group of objects away with respect to the stage (22); a catching section (24) including an adhesion portion (241) to which an object in the group of objects moved from the stage adheres; and an analysis section (3) configured to optically analyze the object caught by the catching section. This makes it possible to efficiently and satisfactorily perform optical analysis of individual microplastics by eliminating manual work of picking up the microplastics one by one.

  • Publication number: 20200400504
    Abstract: Provided is a fixed mirror unit capable of adjusting the inclination of a reflection surface and moving the reflection surface in a direction intersecting with the reflection surface with a simple configuration, an interferometer equipped with the fixed mirror unit, and a Fourier transform spectrophotometer. The fixed mirror unit 8 is provided with a plurality of actuators 83 for axially displacing the mirror 87. By displacing the mirror 87 by different amounts of displacements with the plurality of actuators 83, the angle of the reflection surface 87A can be adjusted, while by displacing the mirror 87 by the same amount of displacement with the plurality of actuators 83, the reflection surface 87A can be moved while keeping the angle of the reflection surface 87A constant. As a result, with a simple configuration, the angle of the reflection surface 87A can be adjusted and the reflection surface 87A can be moved along the axial direction.

  • Patent number: 7692707
    Abstract: In a solid-state image sensor according to this invention, an image signal temperature variation suppressing unit changes a voltage value of a driver voltage applied to multiplying registers in response to variations in sensor temperature of a CCD image sensor. Thus, a charge multiplication gain of a charge multiplying unit is electrically controlled to suppress variations in signal strength of image signals due to the variations in the sensor temperature of the CCD image sensor.

  • Patent number: 7570303
    Abstract: An image pick-up element 1 is mounted on an element mounting part 7 formed with a member whose thermal conductivity is higher than that of an element storing part 3. Inputting and outputting pins 5 for electrically connecting the image pick-up element to a control circuit board 13 for controlling the image pick-up element are provided in a direction that does not interfere with the contact part of the element mounting part 7 and a heat absorbing mechanism 8. Thus, the thermal conductivity of the image pick-up element and the heat absorbing mechanism can be improved and the area of a heat absorbing part can be increased. As a result, the cooling capability of the element is increased so that the image pick-up element can be driven under a condition at higher speed than usual.

  • Publication number: 20040119882
    Abstract: A docking unit that optically couples optical images obtained from a plurality of (e.g. three) cameras includes at least a synchronous control circuit for controlling image pickup timing of the cameras. A camera controller, which performs an overall control, is constructed capable of bi-directional communication with the synchronous control circuit and a coupling circuit in the docking unit. The communication for exchanging signals between the synchronous control circuit and coupling circuit in the docking unit and the camera controller is invariable regardless of the number of cameras. Thus, this construction simplifies the bidirectional communication to and from the camera controller.
