  • Publication number: 20230168513
    Abstract: Disclosed are systems and methods for expanding eyebox for a viewer, including (but not limited to) for the near eye display applying retinal projecting technologies from a head wearable device such as smart glasses. This disclosure includes two embodiments. The first embodiment applying a principle of “light-split” comprises an optical duplicator to generate multiple instances of an incident light signal to achieve eyebox expansion for a viewer. The second embodiment applying a principle of “time-split” comprises an optical reflector moving to redirect multiple light signals at a different angle of incidence to achieve eyebox expansion for a viewer.

  • Publication number: 20230049899
    Abstract: A head wearable display system comprising a target object detection module receiving multiple image pixels of a first portion and a second portion of a target object, and the corresponding depths; a first light emitter emitting multiple first-eye light signals to display a first-eye virtual image of the first portion and the second portion of the target object for a viewer; a first light direction modifier for respectively varying a light direction of each of the multiple first-eye light signals emitted from the first light emitter; a first collimator; a first combiner, for redirecting and converging the multiple first-eye light signals towards a first eye of the viewer. The first-eye virtual image of the first portion of the target object in a first field of view has a greater number of the multiple first-eye light signals per degree than that of the first-eye virtual image of the second portion of the target object in a second field of view.

  • Publication number: 20220413293
    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.

  • Publication number: 20220311992
    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: 9891430
    Abstract: A laser projector includes a laser source module for generating an input light beam, a deflection component that deflects the input light beam to mutually orthogonal first and second scanning directions to form a scanning light beam, a first prism and a second prism both used for allowing the scanning light beam to pass therethrough for performing two-dimensional scanning on an imaging surface and formation of an image. By adjustment of the angle between the first prism and the second prism, various conditions are satisfied to achieve image distortion correction and image lift.

  • Patent number: 7990620
    Abstract: A head-up display system is described. The head-up display system includes an image projection device, a diffusion unit, and a frame demonstration medium. The image projection device emits the visible light, containing text or image information, for generating a real image on the diffusion unit. The frame demonstration medium receives the visible light reflected from the diffusion unit. By adjusting the received visible light reflected from the diffusion unit, the frame demonstration medium generates a virtual image corresponding to the real image. The distance between the real image corresponding to the diffusion unit and the frame demonstration medium is preferably equal to the distance between the virtual image and the frame demonstration medium. Alternatively, the visible light is projected to the frame demonstration medium and then reflected to the diffusion unit.

  • Patent number: 7971790
    Abstract: A laser pointer includes a human-machine interface disposed above the housing for users to control components inside the housing to decide patterns and size of the projecting image. The components consist of a frequency/phase control module, a driving energy control module, a laser beam generating module and a light scanning device. The frequency/phase control module controls the driving energy control module while the driving energy control module controls driving energy of the light scanning device. The size of the image is controlled by change of the amplitude of the light scanning device while the amplitude is changed along with the driving energy. The amplitude may also change along with the driving frequency. When the driving energy is fixed and the driving frequency is close to the resonant frequency, the amplitude increases. On the contrary, the amplitude decreases.
