Abstract: The present disclosure relates to a time-of-flight distance measuring device. The light source (24) includes a plurality of emitting portions (70, 72), each of which illuminates a respective one of the sub-regions (R1, R2). The light receiver (26) includes a plurality of receiving portions (74, 76) corresponding to respective ones of the emitting portions (70, 72). The first controller (28) controls (i) a first emitting portion (70) to emit the emitted light including an Nth-order harmonic component of a fundamental frequency and (ii) a second emitting portion (72) to emit the emitted light including an Mth-order harmonic component. The second controller (30) controls a particular receiving portion (74) corresponding to the first emitting portion (70) to be sensible to the Nth-order Mth-order harmonic components. The multipath detector (82) detects occurrence of the multipath error when the particular receiving portion (74) senses both the Nth-order and Mth-order components.

Abstract: A method for reading a demodulation pixel of a distance sensor for determining a distance, in particular for determining the difference between two charge quantities independently of the total magnitude of the charge quantities, and also a distance sensor are proposed. For faster signal processing, provision is made for applying a variable control voltage to the transfer gates for influencing the potential wall, and lowering the respective potential walls of the corresponding transfer gates, before and/or until from the storage gates in each case charge carriers can surmount the respective potential wall of the corresponding transfer gate and pass to the assigned floating diffusion.

Abstract: The structure i.e. photodetector (1), has a bias-layer (4) made of a semiconductor material and arranged on a rear side of a substrate (2) spaced from a contact area (3) i.e. tub. The contact area is partially laid opposite to the bias-layer. A protective structured guard ring (5) is arranged on a front side of the substrate, and surrounds the contact area. Reverse voltage is applied between the contact area and the ring. An overlap region exhibits lateral dimension, which is quarter of distance between the contact area and the bias-layer. The substrate is made of floating zone silicone.

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.
