Hardware consisting of the uncooled infrared camera, equipped with optical fibers (not shown) connected with the monitor. The device had two unique features, including a wafer-level chip scale vacuum package with a 160 × 120 silicone on insulator-diode array with a detectable wavelength range of 8–12 μm and a real-time signal correction capability with respect to the ambient temperature. It also had distinguishing characteristics with regard to its size (42 × 56 × 43 mm), weight (70.3 g), and temperature resolution (< 0.022 degrees). The output of the uncooled infrared camera was recorded by a digital video recorder.
