Abstract

This invention called "Fiber Optical Ice Detector" (FOID) remotely detects early formation of ice around dedicated optical fibers on structure surfaces. The fibers may be glued to the surface, embedded into it in case of composite materials, or otherwise attached to it. The invention is based on the light diffusion by ice and light reflection from ice boundaries, that optically couple multimode optical fibres in specially built sensitive zones. Such zones may be multiple in order to achieve sensing distributed along the fibers (rather than at a single location). Sensitive zones consist of specially profiled cross sections that amplify the effects involved by allowing most of the light to be modulated. Thus, the invention makes it possible to achieve early detection of small quantities of ice at multiple locations along the fibers. A most widespread use of this invention is expected in the aircraft industry for remote detection of ice formation around critical parts - wings.
