    摘要: An infrared radiation emitter is provided that is capable of producing infrared radiation modulating at high frequency. The IR emitter includes a low-thermal-mass resistive membrane that is suspended by long thermal isolation arms over a substrate. The membrane is suspended over the substrate such that a resonant emitting cavity is formed between the membrane and the substrate. The low-mass, thermally isolated membrane design maximizes the temperature change induced by Joule heating of the resistive membrane and allows the emitted IR radiation to be modulated at high frequencies.
