description: In a radical departure from conventional thermal emitter-based dynamic IR scene simulation devices, we have tested  InAsSbP/InAs LEDs grown by liquid phase epitaxy and tuned at several peak-emitting wavelengths inside the mid-IR  band. 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.
