DIGITALER POSITIONSGEBER

摘要

A position transmitter which determines the point of incidence of a light or particle beam on a sensor array, and the output signal of which gives the point of incidence in a digital code. The position transmitter comprises a sensor array having diodes which are arranged on a substrate and are connected at least partly to each other as well as to a digital bus, of which a part of the array generates electron-hole pairs if the light or particle beam strikes, and another part of the diode array arranged in accordance with the desired code is switched off in its function.
