N2 - A scanning imaging system that simultaneously generates visual or near-infrared (NIR, < 2 μm) and far infrared (FIR, 8 to 12 μm) digitized images is described. The visible or NIR images are presentations of reflected radiation at the corresponding wavelengths. The FIR emission is calibrated with thermostated black bodies to yield a thermal image. The system was designed to produce twin images, with identical perspective and scale factor, that can be overlayed to allow unambiguous identification of the observed object and precise location of thermal features on the observed object. This system has a variety of uses, especially in clinical applications of telethermometry. The visual imaging system is designed to use the same optical scanning configuration as that which generates the thermometric data. The camera's optical scanning system is described, as are the electronics of the imaging system, including the design of the photodiode amplifier, pixel trigger generator, digitizer and the computer interface circuits. A few experimental images taken by this system are also presented.
