Abstract
A computer simulation of the Hadamard beam spectroscopy has been attempted to show its utility and feasibility for various experimental situations in a beam spectroscopy.A simple one-dimensional case to measure spatial beam distributions is demonstrated. In simulations, an incident beam distribution is produced with the aid of a random sampling number, as is conventionally clone just in the Monte Carlo method. The incident beam is encoded by a fifteen-slot Hadamard mask located in front of a detector. Reconstructions of the initial beam distribution from the encoded data are achieved by the process of inverse Hadamard transform. Results of the computer simulation show that the new beam technique by means of Hadamard transform has many of advantages over the conventional point-by-point measuring technique and would be successfully applied to a mass spectroscopy, an energy spectroscopy, or other beam spectroscopic measurements.
