Claim 5:
6. The hyperspectral imaging method according to claim 1, wherein providing the mid-infrared ultrashort pulse as the pump light and the near-infrared ultrashort pulse as the signal light comprises:
separating a laser beam generated by a laser to the mid-infrared ultrashort pulse and the near-infrared ultrashort pulse through a chirped periodically poled lithium niobate crystal;
collimating the mid-infrared ultrashort pulse and the near-infrared ultrashort pulse by a collimator, and
spatially separating the mid-infrared ultrashort pulse and the near-infrared ultrashort pulse by a dichroscope to provide the pump light and the signal light.
