The invention relates to a method for detecting and/or processing signal waves that produce charge carriers in an article sensitive to the signal waves, said charge carriers inducing a signal current in at least one readout electrode. At least two modulation electrodes are provided, at least one of which is disposed in the proximity of the at least one readout electrode or to another readout electrode in such a manner that, depending on the polarity sign of the modulation volatage of the respective modulation electrode, the current flowing across the associated readout electrode is positive or negative. The invention further relates to a device for detecting and processing signal waves. Said device comprises an OEP article that is sensitive to the signal waves, in which article the signal waves produce charge carriers, and at least one readout electrode (AK) that is linked with the charge carrier range of the article. At least two modulation electrodes (MKa, MKb) are provided, at least one of which is disposed in the proximity of the at least one readout electrode (AK) and the other in the proximity either of the same readout electrode (AK) or of another readout electrode (AK2). The aim of the invention is to provide a method and a device that is capable of interlinking various optical and/or electronic signals in a logically digital or analogous manner or to detect the course of optical signals by scanning (time interval measurements). For this purpose, the modulation electrodes are modulated with relatively freely selectable voltage amplitude and/or phase relation, whereby the readout currents produced by the modulation voltages of the two modulation electrode are additively coupled. The inventive device is characterized in that the modulation electrodes are disposed relative to the readout electrode(s) in such a manner that, depending on the polarity sign of the modulation voltages of the respective modulation electrode, the current flowing across the associated readout electrode is positive or negative and that at least one device is provided by which the relative phase relation and/or the voltage amplitude of the two modulation voltages can be freely adjusted.
A method of detecting and/or processing signal waves which in an article sensitive to the signal waves produce charge carriers which induce a signal current in at least one readout electrode, wherein there are provided at least two modulation electrodes, at least one of which is arranged in spatial proximity with the at least one readout electrode and the other modulation electrode is arranged in spatial proximity either with the same readout electrode or a further readout electrode in such a way that in dependence on the sign of the modulation voltage of the respective modulation electrode the current flowing by way of the associated readout electrode is positive or negative, characterized in that the modulation electrodes are modulated with a voltage amplitude and/or phase relationship which can be freely selected relative to each other, wherein the readout currents produced by the modulation voltages of both modulation electrodes are additively coupled.
Apparatus for detecting and processing signal waves, with an article OEP which is sensitive to the signal waves and in which the signal waves produce charge carriers, and at least one readout electrode (AK) connected to the charge carrier region of the article, wherein there are provided at least two modulation electrodes (MKa, MKb) of which at least one is arranged in spatial proximity with the at least one readout electrode (AK) and the other is arranged in spatial proximity either with the same readout electrode (AK) or a further readout electrode (AK2), characterised in that the modulation electrodes are arranged relative to the readout electrode or electrodes in such a way that in dependence on the sign of the modulation voltages of the respective modulation electrodes the current flowing by way of the associated readout electrode is positive or negative and that there is provided at least one device by which the relative phase relationship and/or the voltage amplitude of the two modulation voltages can be freely set.
