POSITION RESOLVED MEASUREMENT APPARATUS AND A METHOD FOR ACQUIRING SPACE COORDINATES OF A QUANTUM BEAM INCIDENT THEREON

摘要

The position calculation of prior art position sensitive detector systems relies on a known geometry pattern of individual electrodes and the distribution of the charge parts. A heuristic estimation is made in order to calculate an initial coordinate of irradiation. In contrast, the present invention allows one to calculate the position of an incident particle in terms of direct mapping of the measured detector response into position coordinates detector surface. The device for estimating the space coordinates of an irradiation position onto a detector comprises a position sensitive detector; an irradiation source; means for measuring the response of detector generated upon irradiation by irradiation source; and an artificial neural network structure provided such that the measured detector response is the input to the artificial neural network structure and the initial space coordinates of irradiation are the output of the artificial neural network structure.
