DEFINITION

Classification: 250/339.08

Including Fourier transform infrared spectrometry:

(under subclass 339.07) Subject matter wherein the detection process includes performing a Fourier transform on the detected signal.

(1) Note. A Fourier transform is a mathematical operation which decomposes a time varying signal into its complex frequency components (amplitude and the phase or real and imaginary components).
