title: Method for numerically enhancing the resolution of certain types of detection systems.
abstract: We present a method for increasing the resolution of detection systems in which the desired information has been convolved with the system instrumental response function and further distorted by the presence of noise. We have written a computer program which can deconvolve the detected signal while treating the noise in a self-consistent manner, allowing to a good degree the reconstruction of the desired signal. We apply this method to reconstruct one component of the ion velocity distribution of a barium plasma. The information is in the form of Doppler-shifted resonance light which is detected and broadened by a Fabry-Perot interferometer. Results are presented and limitations to this method are discussed.
