The invention relates to imaging 3-D time-of-flight sensors that are particularly suitable for the detection of objects and individuals in three-dimensional space. This capability results from the basic principle. In each image point of the sensor, the distance to the object located in the observation space is determined by using the propagation time (time of flight) of light pulses. The sensor therefore supplies a three-dimensional image, which can be analyzed by means of suitable processing algorithms. In specific applications, in particular in the interaction of human and machine, machine and machine, or machine and space, it is necessary that the detection is carried out safely. The level of safety is classified in various standards into safety integrity levels.
A 3D TOF sensor with at least one pixel matrix that has a pixel structure divided into at least two signal paths (channels A and B), wherein the signal paths are routed in such a way that signal propagation times are identical for both signal paths according to a pixel localization and wherein each signal path has its own independent analog signal output (signal A and signal B),
A 3D TOF sensor with an image sensor that comprises an image recorder with a pixel matrix, wherein
