ABSTRACT:
The invention relates to digital scanning imaging by electromagnetic radiation. To reduce the difference between the resolutions in, the scanning direction and the direction perpendicular thereto, pixels (P1, P2, P3, P4, P5, P6) in the scanning direction are connected to counters (C1, C2, C3) through switching means (Sm1, Sm2, Sm3) which allow pulses to be directed to the counter of a neighboring pixel, in addition to its own pixel, for counting, whereby the reading area can be divided into a plurality of “partial pixels” and by suitably changing the switch positions, it is possible to follow the imaging scan as reading areas formed by the “partial pixels”.
