Reduction of stray light noise in optical raman probe sensors

Abstract

A system and method for quantifying the stray light that enters a Raman optical sensor and removes this from the Raman spectrum is disclosed. One or more background noise measurements are performed by the Raman analyzer wherein the laser is disabled during these background noise measurements. One or more traditional signal acquisition measurements are then performed. The results from the background noise measurements and the traditional signal acquisition measurement are then processed. This results in a clean spectrum, where the background noise has been significantly reduced. In some embodiments, background noise measurements are performed before and after the traditional signal acquisition measurement and these noise measurements are averaged.
