Arrangement and method for runtime measurement of a signal between two events

A method for a runtime measurement of a signal between two events, in which method a comparison of one of a time occurrence and a position in a phase of a reference signal on the occurrence of a first event and on the occurrence of the second event is determined, wherein a periodically repeating reference signal is generated by a generator and one of its phase position and time stamp is determined as a first signature for the occurrence of the signal in the first event, the phase position and the time stamp of the reference signal respectively being determined as a second signature for the occurrence of the signal in the second event, and the runtime being determined as a difference of one of the phase positions and the time stamps of the first and second signatures, wherein a physical signal is transmitted by a transmitter, the physical signal is reflected at an object, and generates reflections,

• wherein
• the reflections are received by a sensor matrix that has a plurality of pixels, each having a sensor and a pixel number;
• and
• a trigger signal is generated by a logic from a reflection, which each pixel receives, when a threshold value is exceeded in order to determine the second signature, wherein, to determine the runtime, a look-up table is created on the basis of one of a phase position and a time stamp and is stored in an internal memory.

An apparatus configured for carrying out a method for a runtime measurement of a signal between two events, the apparatus comprising a generator, a transmitter, sensor matrix and a logic, in which method a comparison of one of a time occurrence and a position in a phase of a reference signal on the occurrence of a first event and on the occurrence of the second event is determined, wherein a periodically repeating reference signal is generated by the generator and one of its phase position and time stamp is determined as a first signature for the occurrence of the signal in the first event, the phase position and the time stamp of the reference signal respectively being determined as a second signature for the occurrence of the signal in the second event, and the runtime being determined as a difference of one of the phase positions and the time stamps of the first and second signatures, wherein a physical signal is transmitted by the transmitter, the physical signal is reflected at an object, and generates reflections,

• wherein
• the reflections are received by the sensor matrix that has a plurality of pixels, each having a sensor and a pixel number;
• and
• a trigger signal is generated by the logic from a reflection, which each pixel receives, when a threshold value is exceeded in order to determine the second signature,
• the pixel numbers of the pixels generating a trigger signal are stored in a memory matrix;
• and
• the second signature is determined by the trigger signal and is stored in the memory matrix for all the stored pixel numbers.
