Tendon strain anlysis

We developed a technique for creating maps of the direction and strength of fiber alignment in collagenous soft tissues. The method uses our bioinspired polarization sensor  to measure circularly polarized light transmitted through the tissue. The architecture of the sensor allows measurement of the retardance and fiber alignment at the full frame rate of the sensor without any moving optics. The new technique enables real-time capture of the full angular spread of fiber alignment and retardance under various cyclic loading conditions.
