Rapid multichannel Raman spectrum reconstruction system and detection system

The invention relates to a rapid multichannel Raman spectrum reconstruction system and a detection system. The detection system comprises a stimulation and collection light path and an imaging light path, wherein the stimulation and collection light path comprises a laser generator, a light beam expander, a dichroscope and a micro-objective; the imaging light path comprises a light filter, a firstlens array, a second lens array, a light filter array and an image sensor, which are coaxially arranged; the first lens array and the second lens array are the same in the aspect of structure, and are provided with a plurality of lenses; the light filter array comprises a plurality of bandpass filters corresponding to the plurality of lenses in the aspect of position; the wavelengths selected bythe plurality of bandpass filters are different; and the wavelengths selected by the light filter comprise the wavelengths selected by the plurality of bandpass filters. The device is simple in structure and low in cost, and i
