Intensity values of electromagnetic radiation from an object to be imaged are received from an array of detectors. The array of detectors includes one or more pairs of detectors arranged as antisymmetric pairs of detectors. A Fourier transform of an image of the object is determined by correlating fluctuations of the intensity values for each antisymmetric pair of detectors. An inverse of the Fourier transform is determined, and an image of the object is generated from the inverse Fourier transform.
