Time-resolved spectrum rapid measurement system and method

A time-resolved spectrum rapid measurement system, comprising:

• a pulse laser module, configured to emit pulse laser;
• a sample stage module, configured to focus the pulse laser on samples, then collect signal light produced by the samples, and filter out excitation light;
• a multi-path delay module, configured to split the signal light produced by the samples to form a plurality of optical paths;
• a spectrometer module, configured to spatially distinguish signal light of different wavelengths in each optical path, wherein the multi-path delay module is connected to slits in the spectrometer module, each optical path corresponds to a different position of the slits;
• a 2-dimensional array detector module, configured to detect spatially distinguished signal light of the plurality of optical paths in parallel;
• and
• a control computer module, configured to collect, store, and process the detected signal light of the plurality of optical paths to obtain time-resolved spectra, the control computer module being connected to the 2-dimensional array detector module via a data cable;
• wherein the multi-path delay module is configured to add a different optical distance in each optical path to extend the time for the signal light produced by the samples to reach the 2-dimensional array detector module, and is further configured to make the time for the signal light in each optical path to reach the 2-dimensional array detector module different, to realize multi-path delay;
• wherein each optical path is configured to form a spectral line on a pixel array aligned along a same horizontal or vertical position of the 2-dimensional array detector module, and an interval distance between adjacent spectral lines on the 2-dimensional array detector module is proportional to an interval distance between adjacent corresponding optical paths on the slits.
