Abstract
A remote SERS spectrum detection system and a method thereof. The system includes: a pulsed laser light source, configured to emit Raman excitation light; an optical fiber Raman coupling module, configured to couple the Raman excitation light; the optical fiber Raman probe, configured to transmit the Raman excitation light to an object to be measured to generate a SERS signal light, a backscattered SERS signal light being coupled to a monochromator through the optical fiber Raman coupling module; the monochromator, configured to split the backscattered SERS signal light, to obtain backscattered SERS signal lights at different wavelengths; a high-speed photodetector, configured to convert the backscattered SERS signal lights into time-resolved electrical signals; a processor, for analyzing electrical signals, retrieving a SERS spectrum of the remote object to be measured, and controlling automatic scanning of a grating in the monochromator to achieve clock synchronization.
