The IR-Dual-Band-Camera demonstrator collects simultaneously infrared data in the 3-5 μm (mid-wave infrared, MWIR) and 8-12 μm (long-wave infrared, LWIR) atmospheric windows. The demonstrator is based on a two-layer QWIP focal plane array with 384 x 288 x 2 detector elements. Images are typically acquired with a frame rate of 100 Hz at 6.8 ms integration time and are stored as 14-bit digital data. Two different IR-Dual-Band-Optics were designed and developed: first an 86 mm and 390 mm focal length, F/2 dual field of view optics based on refractive and reflective components and second a pure refractive 100 mm focal length, F/1.5 optics. We present the performance of this IR-Dual- Band-Camera and demonstrate fusion techniques to the pixel-registered dual-band images which show in laboratory tests and field trials promising results with respect to image improvement.
