Abstract: The present disclosure generally relates to laser range finders. In one embodiment, a shallow-trench isolation diode operates in a reverse-biased mode. In another embodiment, a poly-defined diode operates in a forward-biased mode. In both embodiments, the diode emits photons in response to a radio frequency current, and the photons are received by an avalanche photo diode during a calibration process.

Abstract: The invention relates to capturing a still or moving image as well as object position and displacement data for the image, storing the image and the data as a dimension extractable object, and utilizing the dimension extractable object. In one embodiment, the dimension extractable object is used in a method of stitching a plurality of images together to form a stitched image. In another embodiment, the dimension extractable object is used in a method of generating a stitched image from a video image. In another embodiment, the dimension extractable object is used in a method of generating a three-dimensional model from a video image.

Abstract: Embodiments of the present disclosure use an “on chip” silicon LED to generate a light signal for calibration of a range finder. The light signal from the silicon LED may be detected by photo detectors in a reference path and a receive path of the range finder to generate a calibration phase offset, which may be subtracted out from a phase offset measurement of the range finder to correct the phase offset measurement for component mismatch due to, for example, environment, process variation, aging, etc.
