Abstract

Single shot computational ghost imaging (SS-CGI) [1] has been proposed to implement the ghost imaging [2] with only single measurement. In the SS-CGI, a multi wavelength light source is used. And, a spectrometer instead of a bucket detector is put to detect a set of optical intensity. In the conventional CGI, generally, more than a thousands speckle patterns to illuminate a target object are required for imaging. In the SS-CGI, on the other hand, optical distributions of each wavelength correspond with illumination patterns in the conventional one. As a result, measured data set is obtained from the spectrometer with only single shot measurement. Fig. 1 shows a schematic diagram of the SS-CGI. From the figure, double random phase modulation is employed to generate random illumination patterns.
