An optoelectronic measuring system comprises at least two transmission light sources that emit time-sequentially clocked, phased light. A compensation light source is controlled independently of the transmission light sources. A receiver receives the light radiated by the transmission light sources, and the compensation light source converts them into an electrical received signal. At least two evaluation units evaluate the received signal and generate one control signal each. At least two transmission paths each comprise a transmission light source, an evaluation unit and a clock generator. The clock generator generates the clock for the transmission light sources and for the evaluation unit. The evaluation units each generate a control signal. A control unit generates a compensation control signal from the control signals, with which the compensation light source is controlled and supplied. The evaluation unit generates a clock-synchronous control signal for the transmission light source from the received signal.
