Paper Abstract

This paper describes SHAPE TAPE, a thin array of fiber optic curvature sensor laminated on a ribbon substrate, arranged to sense bend and twist. The resulting signals are used to build a 3D computer model containing six degrees of freedom position and orientation information for any location along the ribbon. The tape can be used to derive dynamic or static shape information from objects to which it is attached or scanned over. This is particularly useful where attachment is only partial, since shape tape 'knows where it is' relative to a starting location. Measurements can be performed where cameras cannot see, without the use of magnetic fields. Applications include simulation, film animation, computer aided design, robotics, biomechanics, and crash testing.
