Fig. 4: IR emitter temperature and thermal frequency response.

From: A large-area single-filament infrared emitter and its application in a spectroscopic ethanol gas sensing system

Fig. 4

a Plot of the maximum temperature of the filaments, the mean temperature averaged over a device area of 1.12 mm × 1.25 mm, and the minimum temperature of a device area of 1.12 mm × 1.25 mm against the electrical input power. (b) The thermal frequency response of the emitter, measured with the 3ω method, indicates that the cut-off frequency of the emitter is 4.3 Hz
