Abstract : Scientific results are reported on work directed toward obtaining the understanding of the fundamental principles of photoelectron counting statistics needed for the application of photoelectron counting as a means of demodulating low intensity optical communication signals. A simulated optical communication system featuring a photoelectron counter system was assembled and made functional. A mathematical representation was developed which permits representing photoelectron counts similarly to noisy communication signals. The Poisson transform signal representation, developed previously, was applied to digital filtering. (Author)
