Development of an innovative device for high performance tracking measures

Abstract

In this paper we present a new Weighting Resistive Matrix (WRM) capable of working for a CCD output. The basic idea is that the luminosity of the pixels defines the position error of the pixel itself. In order to reach this outcome, a variable dispersion is performed. A simple way to obtain this is to vary the dispersion width as a function of the input signal’s frequency, proportional to the luminosity of the pixel. This is achieved adding a capacitor to the WRM cell. This new design is capable of performing the straight line fit with a variable position error, as a function of the luminosity.
