Abstract
Devices for providing optical signal transmissions between a transmitter unit and a receiving unit which is mobile relative to the transmitter unit. The units are optically coupled to each other via an optical transfer medium, and thus improve transmission quality by eliminating, or greatly reducing interferences that affect the transmission quality.
Claims7
A device for transmitting optical signals between units movable relative to each other comprising:
- an optical signal transmitting unit comprising an optical transmitter for transmitting optical signals;
- an optical signal receiving unit comprising at least one optical receiver for receiving said optical signals;
- and
- an optical transfer medium for coupling the transmitting unit and the receiving unit;
- said optical signal transmitting unit being movable along said optical transfer medium relative to said signal receiving unit;
- wherein said optical transfer medium is shaped as a closed curve and has a first discontinuity at a position from which two optical signal paths to said optical signal receiving unit are formed and from which the transit times of optical signals along each of said two optical signal paths to said optical signal receiving unit are equal.
