    摘要： An apparatus and method for web inspection utilize simultaneous capturing of reflected and transmitted light images for real-time merging of same. The reflected light and transmitted light image capturing systems are registered with each other in terms of the down-web and cross-web field being imaged. To allow for the simultaneous acquisition of reflected and transmitted light images, the imaged portion of the web is an unsupported span, and the web is tensioned to prevent sagging. The reflected light and transmitted light image capturing systems each include multiple cameras registered with each other in terms of down-web and cross-web imaging field, and the cameras for the transmitted light image capturing are aligned directly with the light source, which outputs light that is incident on the web at an angle.

    摘要： An optical fiber sensing device and fabrication method therefor, wherein a plurality of individual glass fibers included therein is automatically electrostatically aligned. In the preferred embodiment, a rigid, metal-clad insulative substrate is photolithographically patterned and etched to prepare precise metal lines and connecting bus for the accurate placement of the optical fibers. A 10 kv potential between the etched lines and the fibers will attract and align the fibers with the metal lines. While the optical fibers are held aligned with the metal lines, they are secured thereto by a fast drying adhesive and then the potential released. One edge of the substrate with the attached fibers is diced. The ends of the fibers formed by the dicing operation are used as light transmitters or receivers, while the opposite ends of these fibers are connected to respective light sources and photosensing circuits. A droplet sensor may be formed by mating the surfaces of two substrates containing the adhered fibers together, with the fibers of one substrate being adjacent the fibers of the other, but offset by one fiber diameter. A third substrate is arranged so that its fiber ends confront those on the mated substrates. The fibers of the third substrate are connected to a light source and the fibers of the two mated substrates are connected to a photosensing circuit.
