摘要:
A device for detecting body deformations or movements of a solid body (e.g. human body) includes a light source, a light receiver receiving a light signal and detecting its variations, an elastic lightguide, including optical imperfections, optically connected to the light source and light receiver, and attached to the body. The body's deformations effect the lightguide's deformations, producing the variations. The lightguide can be made as a single-piece or multiple-piece, wherein gaps between the pieces function as optical imperfections. The light variations are converted into electrical signals for further processing by a control system that can be respectively programmed. Particularly, the device can be implemented for monitoring/training human spine movements for treatment. Other implementations are measuring a position, displacement, speed and acceleration of the body or its parts relative to each other. The device can also measure stretching, shifting, shearing, twisting and other deformations of the body.
