Light uniformity, radiation apparent temperature (Ta), thermal resistance, and self heating details were characterized at T=300 K in the microscale by calibrated infrared cameras in the 3-5 mm (light pattern) and 8-12 μm (heat pattern) bands. We show that LEDs are capable of simulating very hot (Ta ³740 K) targets as well as cold objects and low observable with respect to a particular background. We resume that cost effective LEDs enable a platform for photonic scene projection devices able to compete with thermal microemitter MEMS technology in testing and stimulating very high-speed infrared sensors used for military and commercial applications. Proposals on how to further increase LEDs performance are given. keywords: LEDs,IR dynamic scene simulation, apparent temperature coverage: Solid State Physics status: final role: author creators_name: Malyutenko, V.
