Raman spectroscopy is a noninvasive, nondestructive analytical method capable of determining the biochemical constituents based on molecular vibrations. It does not require sample preparation or pretreatment. However, the use of Raman spectroscopy for in vivo clinical applications will depend on the feasibility of measuring Raman spectra in a relatively short time period (a few seconds). In this work, a fast dispersive-type nearinfrared (NIR) Raman spectroscopy system and a skin Raman probe were
