Perceptual pulse condition acquisition system and method

The invention provides a perceived pulse condition acquisition system and method, and relates to the field of pulse condition detection. The tunable laser module is used for emitting detection laser to the first optical signal acquisition module and the FBG sensing module; the first optical signal acquisition module is used for obtaining a reference optical signal according to the detection laser and sending the reference optical signal to the processing module; when the force application device applies force to the calibrated part of the user, the FBG sensing module is used for generating a reflected light signal corresponding to the pulse signal of the user based on the detection laser; the second optical signal acquisition module is used for acquiring a reflected optical signal; the processing module is used for obtaining a change value of the central wavelength of the reflected light according to the reflected light signal and the reference light signal and obtaining a corresponding pulse signal according
