Infrared imaging using uncooled focal plane arrays of unreticulated 10- mu m potassium tantalum niobate films

Potassium tantalum niobate (KTN) films, 10- mu m thick, with a nominal Curie temperature of -20 degrees C were formed on polished platinum-coated sacrificial yttria substrates by metalorganic deposition (MOD). These KTN films were used to fabricate focal plane arrays consisting of 128*128 pixels wit...

description Potassium tantalum niobate (KTN) films, 10- mu m thick, with a nominal Curie temperature of -20 degrees C were formed on polished platinum-coated sacrificial yttria substrates by metalorganic deposition (MOD). These KTN films were used to fabricate focal plane arrays consisting of 128*128 pixels with each pixel on 50- mu m centers and 50- mu m/sup 2/. Using f/1 optics and a 2.5-V/ mu m/sup 2/ detector bias, a noise equivalent temperature (NE Delta T) of 0.65 degrees C was obtained for the best 1% of the pixels when the detector and blackbody source operated at 25 degrees C.< >
