There is a myth which says it is a simple matter to "spin-off" military-supported technology into practical civilian hardware. Infrared system developers are particularly vulnerable to this misconception. To be sure, practical applications in the civilian market require vastly different systems which must either be optimized to meet dedicated and specific non-military requirements or are sufficiently flexible to be self-tailored to satisfy many diverse and imaginative uses. Moreover, practical applications require that infrared systems be not only detection devices, but also measuring devices; complete with simple-to-use controls and calibration capabilities. Unlike most military systems, the practical infrared system must have complementary data analysis devices, which can present the sought-after information in a variety of formats to be most beneficial to the user. Finally, all hardware must include extensive software in order to be reliable, and, especially, cost-effective and thus truly optimized for practical applications.
