Optical Fiber Faceplate
Optical fiber faceplates are formed by regularly arranging and fusing tens of millions of optical fibers with diameters of 4~6 μm. Each fiber is a basic image-transmitting unit, drawn at high temperature from a low-refractive-index cladding glass and a high-refractive-index core glass. Light propagates inside the fibers according to the principle of total internal reflection. With a large numerical aperture, strong light-gathering capability, and high resolution, the faceplate can transmit images from the input surface to the output surface with high fidelity. Optically it has a zero-thickness characteristic, making it an excellent optoelectronic imaging device.
