Abstract: An optical motion detecting device for a flight vehicle includes a base, an optical motion sensor and an operating processor. The optical motion sensor is disposed on the base and adapted to capture a plurality of frames. The operating processor is electrically connected with the optical motion sensor. The operating processor analyzes a pattern within the plurality of frames to acquire displacement of the base relative to a reference plane according to a known height value, and the known height value represents a height that the flight vehicle starts to move.

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.

Abstract: The invention provides an optical sensor package. The optical sensor package includes: a printed circuit board (PCB); a sensor disposed on the PCB; a glass cover disposed directly on the sensor; and an aperture disposed on the PCB comprised of a solid perimeter surrounding the sensor and a ceiling having a cut-out section above the glass cover. The cut-out section of the ceiling is smaller in area than the glass cover. The part of the aperture ceiling which overhangs the glass cover is thicker than the remaining part. The optical sensor package further includes an LED die disposed on the PCB, and Kapton tape placed over the ceiling of the aperture.
