Claim 4:
5. The system of claim 1, wherein the scanning interferometer is configured to modulate the received broadband IR light with a resolution of less than 0.5 cm−1, or less than 0.1 cm−1, or less than 0.07 cm−1, or less than 0.05 cm−1; or
wherein the scanning interferometer is configured to modulate the received broadband IR light at scanning rates from 0.1 Hz to 1000 Hz, or from 0.5 Hz to 100 Hz, or from 0.7 Hz to 10 Hz; or
wherein the scanning interferometer is configured to modulate the received broadband IR light with an average power of at least 1 mW, or at least 20 mW, or at least 70 mW, or at least 100 mW.
