Abstract:
A device for generating temporally distant light pulses is provided, the device including at least a first light source for generating a first sequence of light pulses at a first repetition rate, and a second light source for generating a second sequence of light pulses at a second repetition rate. In some embodiments the device includes at least one actuator element which influences the first and/or the second repetition rate, and a control element which charges the actuator element with a periodical modulation signal for periodical variation of the first and/or second repetition rate. A control circuit is also provided including at least a phase detector, a corrective element, a control element, and a superposition element that forms an actuator signal from a modulation signal and an output signal of the control element, and which charges the actuator element with the actuator signal.
