Systems and methods for attenuated total internal reflectance (ATR) spectroscopy

摘要

Systems and methods for attenuated total reflectance (ATR) spectroscopy. The systems and methods may generally involve differentiating an acquired image in a spectral domain, restricting a spectral range of the acquired image, subtracting an average absorbance from the restricted image data, and applying a principal component analysis to extract significant spectral features from the restricted image data.
