| Description |
The purpose of this project is to develop techniques for applying Raman spectroscopy in commercial and industrial settings. Noise reduction, system optimization, and cost reduction are all primary goals of this project, and different methods of achieving these are explored. Experimentation with cooling the CCD, design and optimization of the gas sample cell, characterization of the spectrometer and its various components, and characterization of the source are all discussed pertaining to noise reduction and system optimization. Raman spectroscopy has become a valuable method for analyzing chemical compounds and identifying their various molecular constituents. The Raman effect is weak in gases, making it difficult to detect. Additionally, the Raman signal intensity is about six to ten orders of magnitude weaker than the intensity of the incident light, which makes Raman spectroscopy difficult to implement without highly controlled, laboratory-like conditions. Prohibitive cost of Raman sensing equipment has limited use of Raman spectroscopy for commercial applications. These obstacles are addressed and solutions are proposed. |
