Abstract

A new technique is described which reduces unwanted scattered light and ghosts in Raman spectra. For a perfectly constructed system, the Rayleigh component will be zero, and only the Raman spectra will be detected. This method is far superior to the conventional lock-in, electron counting, and noise power Raman detection techniques.
