The invention relates to a noninvasive blood glucose detection device, system and method, and the device comprises a synchronization and delay module which is used for the synchronization and delay adjustment between a near-infrared picosecond pulse laser module and a time-resolved single-photon detection module; the spatial offset excitation and collection module is used for forming an annular excitation area on the skin surface of the forearm of the hand after near-infrared pulses sequentially pass through a conical lens and a reflecting mirror, and after optical signals emitted from the center of the annular excitation area are collected by a first lens, Rayleigh scattering is filtered out through a band-stop optical filter, and then the optical signals are transmitted to a second lens; the light is gathered to an entrance slit of the spectrometer module by the second lens, and light splitting processing is carried out on the light signal; the time-resolved single-photon detection module is used for detect
