  • Patent number: 11500215
    Abstract: A near-eye display device is provided, including a display light source, a rotation module and a refractive amplification component. The rotation module rotates around the rotation center axis. The rotation module is provided with a light source scanning component and a mirror group. The light source scanning component converts the light of some pixel points of the display light source into radial propagation, and then the light is emitted through the mirror group and the refractive amplification component. The light source scanning component turns the light of some pixel points of the display light source into radial propagation, so that the optical path becomes radial direction from axial direction, and increases the optical path distance without increasing the volume of the device, which is conducive to reducing the thickness and volume of the device.

  • Publication number: 20130077142
    Abstract: A device for image gating using an array of reflective elements is provided herein. The device includes an array of reflective elements, wherein each one of the reflective elements is movable within a range of a plurality of tilt positions, wherein the array is located at an image plane of the device, wherein the array is perpendicular to an optical axis of the device. The device further includes a control unit configured to control the reflective elements such that in at least some of the tilt positions, the reflective elements reflect the radiant flux at said image plane, to one or more projection planes. A gradual rotation of the reflective elements along the plurality of tilt positions result in a gradual increase or decrease in the intensity of the image reflected from the array of reflective elements while maintaining the image integrity.

    Abstract: An electromechanical tilting device including a first and a second electrode structures, shaped, positioned and oriented to define at least partially interdigitated electrodes, and a suspension defining a tilt-containing motion path for the second structure with respect to the first structure. The motion path is selected to cause changes in overlapping regions and overlapping regions' gaps of the interdigitated electrodes. The device is configured such that an increase in one or more voltage bias applied to interdigitated driving electrodes makes a decrease in a total area of overlapping regions of the driving electrodes electrically energetically favorable.

  • Patent number: 8373915
    Abstract: An optical scanning device for scanning a photoreceptor surface with a beam, said optical scanning device having: a light source for emitting the beam; an optical system for causing the beam emitted from the light source to converge; and a deflector that includes a polygon mirror with a plurality of reflecting surfaces and that deflects the beam that has passed through the optical system by rotations of the polygon mirror. Between the deflector and the photoreceptor surface, no optical system for causing the beam to converge or diverge is disposed. The optical system for causing the beam emitted from the light source to converge generates spherical aberration depending on which part of the optical system in a main-scanning direction the beam passes through. The beam enters into three or more adjacent reflecting surfaces of the polygon mirror at a time.

  • Publication number: 20120267517
    Abstract: The invention refers to a compact multispectral scanning system comprising a primary mirror (1) and secondary mirror (2), wherein the mirrors face each other, are adapted to be rotated at the same angular speed in opposite directions, and are tilted with respect to their rotation axes. The primary mirror is concave, the secondary mirror is smaller than the primary mirror and the rotation axes of both mirrors are aligned. This arrangement makes the system more compact than prior art devices and avoids the dependency of the system on the operation frequency.
