The Solar Bolometric Imager (SBI) is an imaging solar telescope assembly that employs a novel single-detector broadband bolometric measurement technique. An uncooled thermal IR imaging detector is coated with a thin gold-black film that absorbs over 98% of the solar spectrum. The absorbed energy is then re-radiated in the thermal IR and sampled by the detector array. This technique [4] provides an evenly weighted integrated responsivity that spans the majority of the solar spectrum (0.2-2.5μm). We present here performance results from the follow-on gold-black deposition process investigation, radiation testing results, spacecraft instrument design and some of the prototype detector/imaging system's flight performance and calibration data from our 2007 Ft. Sumner balloon flight that demonstrates the instrument met or exceeded all of its specification.
