Pulse signal measurement method and device

The invention provides a pulse signal measurement method. The method includes the steps that a first light source and a second light source are set to work at a first light source frequency, and the first light source frequency is different from a second light source frequency of an environment light source; the first light source emits first measurement light to the first body surface skin corresponding to the artery of a measured object and the second light source emits second measurement light to the second body surface skin corresponding to the non-artery of the measured object; first reflection light of the first body surface skin is received and converted into a first electric signal and second reflection light of the second body surface skin is received and converted into a second electric signal; band-pass filtering is conducted on the first electric signal to acquire a third electric signal and band-pass filtering is conducted on the second electric signal to acquire a fourth electric signal; differential treatment is conducted on the third electric signal and the fourth electric signal to acquire a fifth electric signal; according to the fifth electric signal, a pulse signal of the measured object is acquired. The invention further provides a pulse signal measurement device.
