frequency domain [′frē·kwən·sē də‚mān] (communications) A plane on which signal strength can be represented graphically as a function of frequency, instead of a function of time. (control systems) Pertaining to a method of analysis, particularly useful for fixed linear systems in which one does not deal with functions of time explicitly, but with their Laplace or Fourier transforms, which are functions of frequency.

| Spectralis[TM] HRA+OCT is a spectral domain system, sometimes called fourier domain, which scans the retina at 40,000 scans per second, creating highly detailed images of the structure of the retina. The software also easily handles unevenly sampled data with Lomb-Scargle Fourier domain analysis using techniques originally developed by astrophysicists.
