### Operational Overview
The Burleigh WA-7000 operates by analyzing interference fringes produced by input laser radiation in a scanning Michelson interferometer. These fringes are sampled at intervals calibrated by the internal HeNe reference laser. A digital signal processor computes a Fourier Transform of the resulting interferogram to generate the optical spectrum, displaying discrete wavelengths as peaks. The instrument can measure and differentiate up to 200 discrete optical signals, displaying their individual wavelengths and powers.
