Abstract
Coherent infrared (IR) image bundle was developed for the delivery of the IR thermal image. The fiber employed was the As2S3 glass core of 65 μm diam and Teflon (perfluoronated ethylene propylene) cladding of 75 μm diam, which has the transmission range in the wavelength region between 1 and 7 μm. Two kinds of bundles of 100 cm long were prepared, which consisted of 1550 fibers (NPB75-1550) and of 8400 fibers (NPB75-8400). The IR imaging system was constructed by coupling the bundle to an IR television camera. The performance of the system was investigated by detecting the thermal image of an operating LSI package.Keywords
