  • Patent number: 12231613
    Abstract: An object displaying system includes a right light signal generator, a left light signal generator, a right combiner, and a left combiner. The right light signal generator generates right light signals for an object. The right combiner receives and redirects the right light signals towards one retina of a viewer to display multiple right pixels of the object. The left light signal generator generates leftght signals for the object. The left combiner receives and redirects the left light signals towards the other retina of the viewer to display multiple left pixels of the object. A first redirected right light signal and a corresponding first redirected left light signal are perceived by the viewer to display a first virtual binocular pixel of the object with a first depth that is related to a first angle between the first redirected right light signal and the corresponding first redirected left light signal.

  • Patent number: 12099200
    Abstract: Disclosed are systems and methods for superimposing a virtual image on a real-time image. A system for superimposing a virtual image on a real-time image comprises a real-time image module and a virtual image module. The real-time image module comprises a magnification assembly to generate a real-time image of an object at a first location and a first depth, with a predetermined magnification. The virtual image module generates a virtual image by respectively projecting a right light signal to a viewer's right eye and a corresponding left light signal to a viewer's left eye. The right light signal and the corresponding left light signal are perceived by the viewer to display the virtual image at a second location and a second depth. The second depth is related to an angle between the right light signal and the corresponding left light signal projected to the viewer's eyes. The second depth may be approximately the same as the first depth.
