CMOS image sensor for spatiotemporal image acquisition [PDF]
Journal of Electronic Imaging, 2006 We present a 64-×64-pixel CMOS image sensor chip that can acquire a 16-gray-level image containing both spatial and temporal information of the moving luminous object under observation. The image can next be processed using any image processing software in order to determine the speed, trajectory, and direction of motion of the moving object.

An Analysis of Optical Contributions to a Photo-Sensor's Ballistic Fingerprints
, 2018 Lens aberrations have previously been used to determine the provenance of an image. However, this is not necessarily unique to an image sensor, as lens systems are often interchanged. Photo-response non-uniformity noise was proposed in 2005 by Luk\'a\v{s}
