  • Hybrid image-sensing apparatus having filters permitting incident light in infrared region to be passed to time-of-flight pixel
    Patent number: 9348019
    Abstract: An image-sensing apparatus is provided. The image-sensing apparatus includes: an optical filter array including a two-band passing filter and an infrared filter; an RGB pixel array placed below the two-band passing filter; and a TOF pixel array adjacent to the RGB pixel array and placed below the two-band passing filter and the infrared filter, wherein a combination of the two-band passing filter and the infrared passing filter permits only the incident light in the infrared region to pass to the ToF pixel array.

  • Tunable micro-aspherical lens and manufacturing method thereof
    Patent number: 7561340
    Abstract: A tunable micro-aspherical lens is disclosed, which employs two potential differences provided by two sets of electrodes to dynamically change the bottom area and the central height of the liquid polymer lens. The tunable micro-aspherical lens includes a tunable lens, a lower electrode plate, a hydrophobic pattern, an insulation layer and an upper transparent electrode plate. Also, a manufacturing method of a tunable micro-aspherical lens is disclosed, which includes forming a lower electrode plate, forming an insulation layer, determining a position of the tunable lens, controlling the bottom area and the central height of the tunable lens. The tunable micro-aspherical lens of the present invention eliminates spherical aberration and improves the focus spot resolution to shrink the focus spot and thus to provide better optical quality.
