Latest Patents
Wightman holds a patent for a "Method for detecting defects in fibers." This innovative method addresses the detection of defects such as holes or voids in optical waveguide fibers. The technique employs far-field interference patterns produced by transversely illuminating the fiber with a laser beam. Holes in the fiber create a characteristic peak in the spatial frequency spectrum of the interference pattern, which subdivides into two peaks that migrate in opposite directions as the hole grows. Additionally, the presence of holes results in a notable increase in the total power of the interference pattern, with the increase being a linear function of the hole's size for diameters less than about 60% of the fiber's diameter. These detection methods are integrated into a comprehensive system for controlling the drawing of optical waveguide fibers.
