Abstract:
TOF distance sensor for capturing the distance to an object by receiving radiation reflected by the object, said radiation emanating from a radiation source modulated by a modulation frequency, comprising a pixel matrix for recording a pixel image. The pixel matrix consists of demodulation pixels which are designed for rear-side reception of the radiation. The demodulation pixels comprise a conversion region for generating charge carriers from the received radiation, and a separating device for separating the charge carriers in accordance with the modulation frequency, and also a stop for partitioning-off the conversion region from the separating device in relation to the charge carriers, and also an aperture for passing the charge carriers from the conversion region into the separating device. The TOF distance sensor is embodied in such a way that in each case at least two demodulation pixels form a common aperture.
