  • Patent number: 11926064
    Abstract: A remote control manipulator system includes: a manipulator being controlled by an operator remotely to handle an object; a stereoscopic display device that displays a right-eye image and a left-eye image so as to be stereoscopically viewed; a model image generator that generates a model image being an image of an integrated three-dimensional model viewed from a viewpoint designated by the operator, the integrated three-dimensional model being a three-dimensional model obtained by integrating the manipulator model and a surrounding environment model being generated by performing image processing on the right-eye image and the left-eye image and being a three-dimensional model of the object and a surrounding environment thereof; and a model image display device that displays the model image and is configured to be able to be viewed by the operator switching between the stereoscopic display device and the model image display device through moving the head of the operator.

  • Publication number: 20230304891
    Abstract: The wavefront measuring apparatus includes: a first lens array to split a radially propagating light beam after being emitted from an optical system to be tested and once forming an image, and then to condense each of the split light beams; a detection unit, disposed at a position where condensing spots of the plurality of split light beams radially propagating from the first lens array are formed, to detect the condensing spots; and a control unit to calculate, when the first lens array is at a position of conjugation with the optical system to be tested, in other words, the position where the images of the optical system to be tested are transferred, a transmitted wavefront of the optical system to be tested from barycenter positions of the condensing spots.

  • Patent number: 11038590
    Abstract: An optical transmission device includes: a controlled oscillator for outputting a calibration signal having an output frequency that corresponds to an input oscillation control signal; an electrical-to-optical conversion circuit for generating an optical transmission signal by superimposing a transmission signal in a radio frequency band and the calibration signal on an optical wave; an optical input and output unit for sending the optical transmission signal to an optical transmission path and receiving a reflection signal that is a part of the optical transmission signal from an optical reception device; an optical-to-electrical converter for converting the reflection signal into a radio frequency signal; a phase locked loop for generating the oscillation control signal so that radio frequency output of the optical-to-electrical converter is phase-locked with a reference signal input from a reference signal source; and a signal generation circuit for generating, as the transmission signal, the radio frequen
