  • Patent number: 7466398
    Abstract: An optical navigation device and a method thereof, wherein the optical navigation device comprises a pair of linear sensor arrays which are arranged non-parallel to each other for detecting light signal. Furthermore, an algorithm including correlation and vector analysis is processed by a computation unit to determine velocity and displacement according to present and previous light signal data sequences. Hence, the linear sensor arrays adapted to be the approach of navigation device can achieve the goal of reducing the computing data, increasing operation speed effectively and reducing hardware cost because of its fewer optically sensitive elements.
    Type: Grant

  • Publication number: 20080173790
    Abstract: A motion-detecting module with a built-in light source includes a chip unit, a cover unit, and a light-guiding unit. The chip unit has a PCB, a light-emitting chip, and an image-sensing chip. The light-emitting chip and the image-sensing chip are electrically disposed on the PCB. The cover unit is covered on the image-sensing chip, and the cover unit has a first opening for exposing the image-sensing chip. The light-guiding unit is disposed on a bottom side of the cover unit, and the light-guiding unit has a surface having a reflective layer thereon with a concave structure. The surface and the reflective layer are formed a reflective surface for reflecting and condensing beams generated from the light-emitting chip. Therefore, the beams are reflected via the reflective surface to form first beams, and the first beams are reflected via the object surface to form second beams that project onto the image-sensing chip.
