Abstract

The components which go to make up a Brillouin spectrometer are notoriously unstable. Traditionally, one stabilizes these components by controlling their environment and by making use of complex feedback circuits. A simpler approach to the problem of instabilities is to allow them to occur and to correct for their effects on the spectra using a minicomputer. This approach has been applied to a system consisting mainly of standard commercial components.
