1. A light detection and ranging system comprising:
at least one light source for emitting a light pulse to the surroundings of the light detection and ranging system,
at least one a monitoring optical sensor for monitoring the light pulse emitted by the at least one light source, wherein each of the at least one monitoring optical sensor is associated with a corresponding one of the at least one light source and provides a monitor signal related to the light pulse;
at least one receiving optical sensor for receiving a light signal from the surroundings of the light detection and ranging system, each of the at least one receiving optical sensor providing a sensor signal related to the light signal; and
at least one signal processing unit for processing the sensor signal of the at least one receiving optical sensor, wherein each of the at least one signal processing unit receives the sensor signal from an associated one of the at least one receiving optical sensor,
wherein each of the at least one signal processing unit comprises a multiplexer at the input configured to multiplex between the sensor signal of the one of the at least one receiving optical sensor that is associated with the signal processing unit and the monitor signal of at least one monitoring optical sensor,
wherein each sensor signal from each of the at least one receiving optical sensors is processed in a separate signal processing unit of the at least one signal processing unit and each sensor signal is separately multiplexed with the monitor signal in the multiplexor of the separate signal processing unit.
