Abstract: In an optical detection system, received light can be concentrated and presented to a single-pixel photodetector (or an array of relatively few photodetectors). Concentration of received light can be performed by curved concentrator such as a continuously-curved or faceted reflector. A portion or an entirety of the detector might be blinded (e.g., desensitized) by bright interferers such as the sun. An electro-optic shutter such as a liquid crystal (LC) structure can be used to selectively transmit or mask-off portions of the received light. For example, an LC structure can have regions of selectable opacity for a specified polarization of incident light. The LC structure can be controlled to render certain region opaque, such as to suppress interference from unwanted interferers such as the sun, bright lights, or unwanted reflections. An LC structure can also be used to implement a scanned transmit/receive technique.

The generated light can have sufficient luminance to penetrate a predetermined depth of water and to saturate at least one pixel of the image sensor.

Abstract: In some embodiments, images for the video conference may be white balanced. White balancing may include dividing at least a subset of an image's pixels into multiple ranges according to their luminance and chrominance values. For example, at least a portion of the pixels in an image may be sorted into different groups (i.e., by incrementing counters respective to each group) according to the luminance and chrominance values of the pixels. If enough pixels are found to be in a particular group, a portion or all of the image may be adjusted by a ratio corresponding to that particular group. For example, blue and red analog gains (corresponding to the selected pixels) may be modified by a corresponding ratio to bring red and blue accumulations closer to green accumulations.
