摘要

The precision length measurement method uses a signal generator (18,20) that delivers a pulse into an electromagnetic transmission line (24) along which is movable a target (28) adapted to produce a partial signal reflection at the position along the line at which it is located. A bistable device (10) detects the reflected signal and processing means (12,14,16) provides an output precisely representative of the length of transmission line (and thus of an article or object along which the line is disposed) between its input end and the target.
