Abstract: Various embodiments relating to reducing camera interference are disclosed. In one embodiment, an infrared image of a scene may be received from a camera that emits infrared light. An interference condition likely to degrade infrared performance of one or more proximate infrared devices may be recognized. Responsive to recognizing the interference condition, an instruction to mitigate the interference condition may be output.

Abstract: A method to calibrate an imaging array of a time-of-flight depth camera includes the act of modulating emission from a light source of the camera while synchronously biasing the imaging array. In this method, the modulated emission reflects from a compact reflector positioned a known distance from the camera and passes through an optical diffuser en route to the imaging array. For each pixel of the imaging array, a correction term is stored, which brings the output from that pixel into agreement with the actual distance between the camera and the compact reflector.

Abstract: Spatial sampling is a key factor in determining acquisition parameters for seismic surveys. Acquiring the data to meet spatial sampling requirements for low, mid and high frequencies, by acquiring coarse, medium and fine acquisition grids respectively and layering these during processing, can result in reduced cost and/or higher quality surveys.
