Two-dimensional reduction

This technique allows two-dimensional reduction of noise without using a digital computation technique. The precision in signal measurement is improved by a factor of 16. Other spectrometric techniques have been developed to improve the enhancement factor, e.g., by using a Mach-Zehnder interferometer or an intracavity quenching effect.
