Cameras are often marketed in terms of the number of pixels they possess – the more pixels the “better” the camera. Rather than increasing the number of pixels we ask the questions “how can a camera work with a single pixel”. This talk will link the field of computational ghost imaging to that of single-pixel imaging explaining how spatial structuring of either the illumination or imaging system means that image and video reconstruction can be achieved using just a small number of photodiodes.
Such approaches are particularly useful for imaging at wavelengths where detector arrays are either very expensive or unobtainable.
