Abstract: Techniques are disclosed for laser-based bore sighting, enabling wind sensing to be performed on captured images of the laser spot. Techniques can include image averaging, background subtraction, and filtering to help ensure that the Gaussian laser spot is detected in the image. Embodiments may include defining a bounding region and altering the operation of a camera such that the camera does not provide pixel data from pixels sensors corresponding pixels of outside the bounding region in subsequent image captures. Embodiments may additionally or alternatively include extracting two stereoscopic images from a single image capture.

Abstract: A method and system for optoelectronic receivers utilizing waveguide heterojunction phototransistors (HPTs) integrated in a CMOS SOI wafer are disclosed and may include receiving optical signals via a top surface of a photonically-enabled CMOS chip; and generating electrical signals in the chip utilizing one or more HPTs that detect optical signals. The HPTs may comprise a base and a split collector, with the split collector comprising a silicon-on-insulator (SOI) layer and a germanium layer. The thickness of the germanium layer may be such that carriers in the base do not interact with defects from an interface between the SOI layer and the germanium layer. The electrical signals may be amplified by amplifiers, the outputs of which may be utilized to bias the HPTs by a feedback network. An electrode formed longitudinally in the direction of light travel through the HPTs may bias the base of the HPTs.
