  • Patent number: 11690500
    Abstract: A stereo-endoscope for observation and analysis of an object, comprising a shaft with distal and proximal ends, illuminating means for illuminating the object, and stereoscopic imaging means which transfer light radiated by the object from the distal end to the proximal end. Light of a first imaging channel is fed into a first sensor, and light of a second imaging channel is fed into a second sensor. Both sensors contain mutually different beam splitters, which split the light into four light beams. One light beam from each of the sensors is deflected onto one sensor each; these two sensors are identical. The signals detected there are assembled to form a stereoscopic image. The stereo-endoscope comprises mutually different manipulating means for the other two light beams; by means of suitably-tuned image-processing algorithms, two different monoscopic images containing information complementary to each other and to the stereoscopic image are generated.

  • Patent number: 9377376
    Abstract: A test apparatus for electro-optical printed circuit boards having optical waveguides comprises a control device, a beamer and a camera, which can be positioned in such a way that light emitted by the beamer can be coupled by means of a first deflecting element to optical waveguides of the circuit board and can be coupled out by means of a second deflecting element into the field of vision of the camera. The beamer is used in a first phase to determine the position for each deflecting mirror of the first deflecting element which a light spot needs to assume in the image projected by the beamer so that the light spot illuminates the deflecting mirror. The beamer is used in a second phase to illuminate at least one deflecting mirror and to carry out the testing of the optical waveguide associated with the at least one deflecting mirror.
