Abstract
The disclosed invention is a method and apparatus to generate random numbers. The invention is based on the fact that incoherent light source produces certain distribution of wavelength and wide range of emitting angle. The method includes steps of registering a detection event from a random process, identifying a particular photon detection location on the array of photo-detectors after deflected by the grating, in which the photon hits the detector, associating a value with the identified location of photo-detector, and outputting a random number based at least upon the associated value.
