|Smoke and Mirrors: Ultra-Rapid-Scan FT-IR
The data from very-rapid-scan systems will have important differences from
conventional FT-IR data. This slides shows that in a conventional system operating at a
mirror velocity of 6 cm/s appropriate for an MCT detector, the modulation frequencies of
mid-IR radiation will range from 2.5 to 25 kHz, while a HeNe reference laser will be
modulated at 100 kHz.
