Raman spectroscopy
Raman spectroscopy analyzes substance composition using the optical properties of scattered light (Raman scattering) generated upon light irradiation. It non-destructively and non-contactly measures molecular structure and quantity without requiring sample pretreatment. Consequently, it is gaining attention in various fields, notably in medicine. Recently, more flexible measurements, such as in vivo data acquisition using optical fiber probes, have become possible [1].Aiming to establish a joint diagnostic technology utilizing Raman scattering, we have been developing a near-infrared Raman spectrometer connected to an optical fiber probe. Transdermally obtaining Raman spectra of joint components requires an optical probe that efficiently collects Raman scattered light while accounting for skin thickness. In this study, we attempted to improve the optical probe by evaluating optical fiber selection and designing a light-focusing system at the fiber tip.
