Correlation spectrometers like the [[Michelson interferometer]] vary the time lag between signals obtain the power spectrum of input signals. The power spectrum <math>S_{\text{XX}}(f)</math> of a signal is related to its autocorrelation function by a Fourier transform:<ref name="Harris">[http://www.sofia.usra.edu/det_workshop/papers/session4/4-04harris_edjw021022.pdf ''Spectrometers for Heterodyne Detection''] {{webarchive |url=https://web.archive.org/web/20160307051932/http://www.sofia.usra.edu/det_workshop/papers/session4/4-04harris_edjw021022.pdf |date=March 7, 2016 }} Andrew Harris</ref>
