Abstract

Confocal Raman spectroscopy (CRS) technology has wide applications, especially in the biomedical field. CRS provides non-destructive, contrast-free and molecule-specific quantitative measurement of samples, including biological tissues. These advantages make it ideal for human skin characterization. We present a portable dual-wavelength CRS system with a handheld measurement probe which connected to the console by optical fibers. To achieve fast switching between the two wavelengths, a fast 2-to-1 fiber array multiplexing module was used. A large bandwidth could be covered at each measurement point in real time. We performed system characterization for this proposed CRS system and measured different samples.
