Virtual Spectral Selectivity in a Modulated Thermal Infrared Emitter with Lock-In Detection
The need for affordable low-power devices has led MEMS-based thermal emitters to become an interesting option for optical gas sensors. Since these emitters have a low thermal mass, they can be easily modulated and combined with a lock-in amplifier for detection. In this paper, we show that the signa...
