Abstract
A system for detecting forces on and measuring deformation of an anthropomorphic test device (ATD) includes a plurality of body parts and at least one optical fiber supported by and in contact with at least one of the body parts. The body parts form the ATD and simulate at least a part of a human body and the articulation of the human body. The optical fiber extends between a first end and a second end and comprises a plurality of sensors disposed between the ends. An emitter is in communication with the optical fiber for emitting a light having a predetermined band of wavelengths through the optical fiber that is reflected by the sensors and an interrogator is in communication with the optical fiber for detecting the reflected light from the sensor such that changes to the reflected light indicate a strain on the at least one body part.
