摘要：A non-contacting rotary joint for transmitting an input signal guided within an input optical waveguide has an electrical transmission line and a probe. The transmission line has an even number N≧4 of equal length transmission line segments. The optical waveguide is connected to an optical distribution network which has an optical power
splitter for splitting the input signal into N or N/2 individual signals of equal optical power. These signals are forwarded to opto-electrical converters to generate electrical signals for driving the electrical transmission line. The lengths of the optical transmission lines are adjusted so that the propagation time of the optical signal from the end of the input optical waveguide to the end of each individual optical transmission line is approximately the same.
