Paper Abstract

A system has been developed that reduces the effective integration time of an off-shelf RS-170 optomechanical scanning imaging radiometer by two orders of magnitude. The system can be used to image repetitive thermal events at frequencies up to 4 kHz, without aliasing. The effective integration time of the system is 125 μs/frame. Examples include in-cylinder engine combustion and heat transfer in a transistor operating at 2.5 kHz.
