Реферат: The invention concerns a method and corresponding device for determining the phase and/or amplitude data of an electromagnetic wave. In order to bring about the spatial depth resolution of the image data obtained with such a method, the method according to the invention comprises the following steps: an electromagnetic wave is beamed onto the surface of a photonic mixed element comprising at least one pixel, the pixel having at least two light-sensitive modulation light gates G am and G bm and associated accumulation gates G a and G b; modulation light gate voltages U nm(t) and U bm(t), which are configured as U am(t) = U o + U m(t) and U bm(t) = U o - U m(t), are applied to the modulation light gates G am and G bm; a direct voltage, whose magnitude is at least the same as that of the total of U o and the amplitude of the modulation voltage U m(t), is applied to the accumulation gates G a and G b; the charge carriers produced in the space charge region of the modulation light gates G am and G bm by the incident's electromagnetic wave are subjected, as a function of the polarity of the modulation light gate voltages U am(t) and U bm(t), to the potential gradient of a drift field and drift to the corresponding accumulation gate G a or G b; and the charges q a and q b which have drifted to the accumulation gates G a and G b, respectively are diverted. The corresponding photonic mixed element has at least one pixel which comprises at least two light-sensitive modulation light gates (G am, G bm) and accumulation gates (G a, G b) which are associated with the modulation light gates and are partitioned with respect to the incident electronic wave. A plurality of photonic mixed elements can be assembled to form an array.
