Measurement system and method for evaluating time of flight of light
The device has a control signal generator, a light transmitter which generates a light signal with a defined phase relationship to the control signal, and a light receiver. An evaluation unit (16) determines the propagation time between transmitter and receiver. The evaluation unit includes a synchr...

Summary: | The device has a control signal generator, a light transmitter which generates a light signal with a defined phase relationship to the control signal, and a light receiver. An evaluation unit (16) determines the propagation time between transmitter and receiver. The evaluation unit includes a synchronous rectifier controlled by the control signal, to process the output signal from a light receiver (14), and outputs an evaluation signal based on the optical propagation time. An Independent claim is included for a method of evaluating the light propagation time of a light signal. |
