Spatially offset Raman spectroscopy (SORS) is a technique that allows for the analysis of materials beneath the surface by measuring the Raman signals collected at a distance from the point of excitation. This method enhances the ability to probe deeper layers of samples without needing invasive techniques, making it particularly useful in biomedical applications and for the analysis of biological tissues. By collecting scattered light from different spatial offsets, SORS enables improved detection of compounds that may be otherwise obscured by surface layers.
congrats on reading the definition of Spatially Offset Raman Spectroscopy. now let's actually learn it.
