Improved design for fast modulating IR sources

The simulation and characterization of a low-cost IR source are described. The IR emission is obtained from heated thin film resistors which are either self- suspended or deposited an a membrane, The simulation, performed with a finite difference method, shows that a reasonably good modulation can be obtained at 50 Hz and higher, Such specifications meet the requirements of various IR gas sensors such as photoacoustic sensors.
