Abstract

Apparatus for determining distance comprising a transmitting unit for emitting a light pulse, a receiver matrix having at least one photoelectric element and a control unit, wherein the receiver matrix has a first and a second integrator which are connected to the photoelectric element, which are activatable independently of each other and which are each adapted to integrate a measurement signal outputted by photoelectric element over a period of time predetermined by the control unit and thereby to form an integrator state and to output the integrator state as an output signal.
