Abstract
Described are a device for determining a distance to an object, having a transmitting device for emitting signals, a receiving device for receiving signals and for generating detection signals, an evaluating device for evaluating the detection signals of the receiving device, and a control device for controlling the evaluation of the detection signals, and a corresponding method. The receiving device has a plurality of receiving elements which generate, in case they receive a signal, a detection signal each. The evaluating device determines the distance to the object in accordance with the time-of-flight method and while considering coincidence events and uses that case in which a number of detection signals generated within a presettable coincidence time at least equals a presettable coincidence depth, as a coincidence events. The control device is configured to determine, starting from a background radiation measurement, a new value for the coincidence time and/or, if applicable, the coincidence depth and preset same for the evaluating device, wherein, in a background radiation measurement, the receiving device receives signals and generates background radiation detection signals.
