Abstract
(EN)
A Raman spectroscopy system is provided. The spectroscopy system includes an optical switch including a pump inlet, a return outlet, a plurality of pump outlets, and a plurality of return inlets. The spectroscopy system includes a plurality of radiation sources optically coupled to the pump inlet of the optical switch, and a detector optically coupled to the return outlet of the optical switch. The spectroscopy system further includes a plurality of probes, each probe optically connected to at least one of the plurality of pump outlets of the optical switch by at least one excitation fiber and optically coupled to one of the return inlets of the optical switch by at least one emission fiber.
