POSITION-SENSITIVE RADIATION DETECTOR

摘要

22 In a position-sensitive radiation detector having a semiconductor body which at least in the operating condition comprises a high-ohmic zone between two radiation-sensitive diodes provided with connection electrodes, a high-ohmic zone between two semiconductor zones provided with connection electrodes, can be apparently centred by varying the voltages at the connection electrodes in such a manner that the photocurrents through the diodes are the same. The signals derived therefrom can be supplied to measuring and control systems for, for example, optical reading and writing apparatus and other measuring apparatus.
