Abstract: An optical detector comprises a plurality of pixels, each pixel comprising a photodiode operable to detect light incident on that pixel and to generate a signal indicative of an intensity of that light. The plurality of pixels comprises a plurality of pixel pairs, and for each pixel pair, in a configuration mode, the detector is arranged to compare the signal generated by a first pixel of the pair with the signal generated by a second pixel of the pair. A method of optical detection is also described, as is a system incorporating the described optical detector.
