A transparent optical cable 5 including a flexible core 5a and a flexible but stiffer cladding 5b transmits light signals axially through the core. When a transparent contact plate 7 or roller 10 depresses and flatteningly distorts the cable, the light signals leak out through the core-cladding interface at the depressed portion and are transmitted through the plate or roller to a photoelectric transducer 8 or 12 mounted on the plate or proximate the roller on a movable object 1, which converts the light signals to electrical signals. Signal transmissions into the cable are also possible, and the input-output signal coupling depression may be made at any point along the length of the cable. |
