Abstract
Innovative mid-infrared imaging fiber bundle has been developed that is flexible, rugged and high fiber-count for use with infrared cameras for thermal imaging applications. High-quality chalcogenide fibers are used to produce coherent fiber bundle that is 2 meters in length, 4000 fibers in a 3mm diameter bundle, minimum bend radius of 10cm, and low attenuation over the spectral range of 1.5-6.5 microns. Individual fiber pixel size is 34 microns and the NA is 0.3. This paper presents the fabrication process and the optical characterization of the mid-infrared imaging fiber bundle.
