ABSTRACT:
The invention relates to a circuit arrangement for a position sensitive radiation detector which produces a current or voltage signal (U.sub.Y) that depends exclusively on the coordinates x and y of the point of incidence of electromagnetic radiation on the EMR sensitive surface of a lateral diode (1). For this purpose, the circuit arrangement has integrators (4, 5), in which the voltages (U.sub.1, U.sub.2) are formed, which are proportional to the integral over time of the output currents (I.sub.1, I.sub.2) of the lateral diode (1). The difference between the voltages (U.sub.1, U.sub.2) is used as a signal, which depends exclusively on the coordinates at that particular time, at which the arithmetic mean of these voltages (U.sub.1, U.sub.2) has reached a preselected, constant value.
