Fourier Transform IR (FTIR)

Fourier Transform IR (FTIR). Most modern IR absorption instruments use Fourier transform techniques with a Michelson interferometer . To obtain an IR absorption spectrum, one mirror of the interferometer moves to generate interference in the radiation reaching the detector.

Frequency Analysis

Frequency Analysis. Fourier analysis deals with the representation of signals by sinewave components. The simplest type of Fourier analysis is that of the Fourier series where a periodic signal x(t) is represented as a sum of sinewaves.
