Abstract
A fiber-optic sensor () is configured to detect curvature of an article (). The sensor includes at least one light source (), at least one optical fiber () and at least one receiver (). The optical fiber () has at least one longitudinal portion () in which the refractive index for light at a predetermined wavelength is reduced with respect to the remaining longitudinal portions. A method for detecting curvature of an article such as a data glove () or an endoscope may utilize such a fiber-optic sensor.
