Abstract
An optical fiber system for a body part of an anthropomorphic test device is disclosed that includes at least one body part and at least one optical fiber that has a plurality of cores in a spaced and parallel relationship with one another that extend between ends of the optical fiber for sensing positions of the at least one body part. Each of the cores have a plurality of grating sensors disposed along a length thereof capable of determining a position and orientation of the body part.
Claims19
A system for detecting forces during a collision test, said system comprising:
- a plurality of components forming a part of at least one of a vehicle, a testing stand, and/or an anthropomorphic test device;
- at least one optical fiber supported by and in contact with at least one of said components with said optical fiber extending between a first end and a second end;
- said optical fiber having a plurality of cores extending between said first and said second ends, each of said cores having a plurality of grating sensors inscribed integrally therein with said sensors spaced along a length between said first and said second ends;
- an emitter in communication with said optical fiber for emitting a light having a predetermined band of wavelengths through said plurality of cores of said optical fiber that is reflected by said sensors;
- and
- an interrogator in communication with said optical fiber for detecting said reflected light from said plurality of grating sensors such that changes to the reflected light indicate a strain on said optical fiber;
- wherein said plurality of cores are further defined as being in a spaced and parallel relationship with one another between said first and said second ends.
