The academic meanings of infrared imaging fiber bundles were researched and their fabrication technologies were given. A kinds of flexible chalcogenide infrared imaging fiber bundles were fabricated, and their characteristics were tested. By taking As40S58Se2 and As40S60 as the rod and tube materials, the fibers were drawn by rod-in-tube technique. The infrared imaging fiber bundle with a core diameter of 40 μm and a cladding diameter of 50 μm was prepared by man-machine-integration technique and it shows squared arrangement which incorporates 576 individual fibers. A special experimental equipment was constructed. The properties of this imaging fiber bundle including spatial arrangement and shaping, blind-fiber ratio and optical transmission efficiency were measured, and the decrease of Modulation Transfer Function (MTF) in the system caused by infrared imaging fiber bundle were measured. Experimental results indicate that the fiber bundle shows a good spatial arrangement and shaping. The blind-fiber ratio is 2.7%, fiber attenuation loss is lower than 0.5 dB/m, and the optical efficiency is almost 31%. Moreover, The decrease of MTF resulted from the fiber bundle in the system is less than 10%. Finally, an infrared imaging experiment was implemented, and the result shows that fine infrared thermal images have been delivered through this system.
