Paper Abstract

In infrared scanning imaging system, long linear-array detector is needed for large field of view. Instead of using long linear-array detector, we couple a non-conventional Infrared (IR) fiber bundle to a small scale Infrared Focal Plane Array (IRFPA) whose format is 320×256 in system to implement 1024×4 format linear array imaging. The input of fiber bundle is long linear array while output is plane-array. Fibers in IR fiber bundle are one to one mapping. Input end of fiber bundle is set at the focal plane of telescopic objective in system, and output end is coupled to IRFPA by coupling lens. By calibrating the position of each fiber in IRFPA, together with the mapping relationship between input and output of fiber bundle, a look up table is established. With the table, we can reconstruct the line object image. According to the scanning period of system, we can get the infrared scanning image.
