Systems and Methods for Correcting Optical Reflectance Measurements
- Magazine Article
Optical spectroscopy can be used to determine the concentration of chemical species in samples. The amount of light absorbed by a particular chemical species is often linearly related to its concentration through Beer’s Law. For nontransparent materials such as powders, tablets, natural materials (soil), blood, skin, and muscle, optical information can be collected via diffuse reflectance spectroscopy.
