Abstract

Centroiding is investigated as a simple and computationally fast technique of image reconstruction, at low light level, of a randomly translating image. The detected frames are sorted by their number of photons, centroided, separated averages performed and then compared with the usual way of centroiding frames. An algorithm for retrieving the phase for one-dimensional centroided imaging is presented and computer simulated data is used to test the theory and the reconstruction technique.
