N2 - Bundles of silver halide optical fibers have been fabricated by extrusion of preforms containing core-clad fibers. Silver halide fibers are transparent in the mid-IR spectral range (2-20μm), and therefore ordered arrays of such fibers have the potential to deliver thermal images at room temperature. Several kinds of bundles were prepared, consisting of 100 to 2500 fibers, with a fill factor of 0.34. Thermal images were delivered through the bundles and recorded using a IR cooled camera. This paper discusses the optical properties and the imaging characteristics of bundles with several fiber densities of 3-160 fibers per mm2 and lengths up to 30cm. The modulation transfer function (MTF) of the bundles was measured by the knife edge sampling process, and by "bar-chart" imaging. The maximum spatial frequency that could be resolved after passing through a typical bundle was 3.5 lines per millimeter.
