Patent ID: 8605261

Claim:
Device for the determination of distance by means of light pulses, comprising: a light source for the emission of light pulses with a certain frequency; a detector for receiving the light pulses emitted and reflected by the light source; and a controller which is in communication with the light source and the detector, and which can control them by means of signals; at least two timers which are connected to the controller and the detector, where the controller is designed such that, when a light pulse is emitted by the light source, it generates a start signal which triggers the time measurement by only one of the at least two timers in order and beginning again from the start; and where the detector is designed so that, upon receiving a reflected light pulse, it generates a stop signal which is routed to the at least two timers, and which stops the time measurement by the timer of the at least two timers to which a measurement window is assigned temporarily by the controller.
