With Successive Reflections Patents (Class 359/857)
  • Patent number: 11397330
    Abstract: An optical device comprises two flat plates each having a reflective flat surface, and two flat spacer plates of thickness H each having a reflective sidewall. The flat plates and flat spacer plates are arranged as a stack with the reflective flat surfaces facing each other and the flat spacer plates arranged in a single plane and disposed between the two flat plates with the reflective sidewalls facing each other and with a gap between the two reflective sidewalls. The facing reflective flat surfaces and facing reflective sidewalls define a light tunnel passage with dimension H in the direction transverse to the single plane. The facing reflective sidewalls may be mutually parallel and spaced by a constant gap W to provide a light tunnel passage with constant cross-section H×W, or may be oriented at an angle to provide a tapered light tunnel passage.

  • Patent number: 10942360
    Abstract: Display systems for achieving collimated projection effects. For example, in a theatrical or concert installation, display systems can be used to project images of scenery that appear to be vast and at a great distant behind the viewing window. The system may include a flat panel display, a corrective mirror, and a concave mirror positioned for viewing by an observer. The corrective mirror pre-warps an image generated by the flat panel display and reflects the undistorted image onto the concave mirror such that the observer perceives the image generated by the flat panel display as being at a large distance. The corrective mirror does not distort with changes in viewpoint. In another implementation, the system may include a short throw projector generating an image, a free-form projection screen, and a concave mirror positioned for viewing by many observers through a viewing window.

  • Patent number: 9152056
    Abstract: An imaging optical system includes a plurality of mirrors that image an object field in an object plane into an image field in an image plane. At least one of the mirrors is obscured, and thus has an opening for imaging light to pass through. The fourth-last mirror in the light path before the image field is not obscured and provides, with an outer edge of the optically effective reflection surface thereof, a central shadowing in a pupil plane of the imaging optical system. The distance between the fourth-last mirror and the last mirror along the optical axis is at least 10% of the distance between the object field and the image field. An intermediate image, which is closest to the image plane, is arranged between the last mirror and the image plane. The imaging optical system can have a numerical aperture of 0.9. These measures, not all of which must be effected simultaneously, lead to an imaging optical system with improved imaging properties and/or reduced production costs.

  • Patent number: 8562156
    Abstract: The present invention relates to a mirror and mirror system which can be used in connection with large vehicles, such as school buses, to provide the driver of such vehicles with the ability to view the entire side of the vehicle. While such vehicles currently include side view mirrors attached to the front of the vehicle, these mirrors contain blind spots, such as the area immediately in front of the rear wheel of the vehicle. The current invention overcomes such blind spots by attaching a second mirror to the rear portion of the vehicle that provides a forward view from the rear of the vehicle, including a view of such blind spots. Such front and rear mirrors may be aligned so that the view of the rear mirror is portrayed within the view of the front mirror. As such, the present invention provides the driver with a complete view of the passenger side of the vehicle.

    Abstract: An optical module is disclosed. The optical module includes: (1) a mirror part for controlling its reflection angle in an analog method; (2) an aperture for controlling an amount of light incident to the mirror part, the aperture being installed facing the mirror part; (3) a detector for detecting an optical signal from a light transmitted from the mirror part; (4) a beam emitter for emitting a beam, the beam emitter being adjacently installed to the optical signal detector; and (5) a controller for controlling the mirror part so as to locate an object, detected by the optical signal detector, at the center portion of the optical signal detector, and for controlling the beam emitter and the mirror part so as to emit a beam from the beam emitter to the object detected by the optical signal detector. The optical module can observe an object both in a wide field of view (FOV) and in detail, effectively track a rapidly moving object, and emit a beam to the object.
