  • Publication number: 20230393407
    Abstract: An optical mouse operated with respect to an illuminated surface outside the optical mouse is provided. The optical mouse includes a light source configured to emit a light beam, and a light pipe including a first optical element and a second optical element. The light beam enters the light pipe through the first optical element, and then propagates in the light pipe from the first optical element to the second optical element without reflection, and then leaves the light pipe through the second optical element, and then illuminates the illuminated surface. The light pipe does not have any protrusion extending therefrom and attached to a front surface of the light source.

  • Patent number: 10704904
    Abstract: A distance detection device includes a light source, a light guiding component, an image sensor and a processor. The light guiding component is disposed adjacent to the light source and includes a discontinuous surface. The light guiding component is adapted to project a beam emitted from the light source onto an object to form an illuminating pattern spotted by the discontinuous surface. The image sensor is adapted to capture an image about the object. The processor is electrically connected with the image sensor and utilized to analyze position variation of a spot formed by the discontinuous surface within the image for determining a distance of the object.

  • Patent number: 8534876
    Abstract: An optical sensor assembly is disclosed. The optical sensor assembly includes an illumination system that segments light emitted by a light source into multiple segments. The multiple segments are allowed to travel different optical paths on their way to a common target area and are further allowed to irradiate different portions of the common target area. This enables a low-profile optical sensor assembly to be achieved.
