  • Publication number: 20200204764
    Abstract: A display device includes an array of light emitters and a mirror configured to reflect light from the light emitters toward an image plane. The display device further includes a controller configured to control the array of light emitters and the mirror to sweep the mirror through a range of angles, and selectively enable the light emitters during sweeping of the mirror. The selective enablement of light emitters, and the sweeping of the mirror, are configured to cause emitted light from the light emitters to project a plurality of pixels on/toward the image plane, with the pixels being spaced with a non-uniform resolution.

  • Publication number: 20200177776
    Abstract: An imaging system comprises one or more optical sensor arrays with separate first and second sensor elements, an objective lens system, a polarization filter system, and associated logic. The objective lens system is configured to direct light received at a given angle onto the first sensor element and onto the second sensor element. The polarization filter system includes a first polarizer portion positioned to filter the light en route to the first sensor element and a second polarizer portion positioned to filter the light en route to the second sensor element, the first and second polarizer portions providing unequal relative attenuance of nonparallel polarization components of the light received at the given angle. The logic is configured to compare intensity of the light directed onto the first sensor element relative to the light directed onto the second sensor element.

  • Publication number: 20200177784
    Abstract: An imaging system comprises an optical sensor array with a plurality of sensor elements, an objective lens, an active polarization filter, and associated logic. The objective lens is configured to direct light from a field of view onto the plurality of sensor elements. Switchable electronically between first and second operational states, the active polarization filter is positioned to filter the light en route to the optical sensor array. The active polarization filter provides unequal relative attenuance, in the first versus the second operational state, of nonparallel polarization components of the light. The logic is configured to switch the active polarization filter from the first operational state to the second operational state, and to compare a light-intensity response of the plurality of sensor elements in the first operational state to the light-intensity response of the plurality of sensor elements in the second operational state.
