摘要:
A photoelectric type pulse signal measuring method includes, obtaining a main-path light signal transmitted by a photoelectric transmitter and reflected back from a surface of skin having an artery underneath, obtaining at least one auxiliary-path light signal receiving an ambient light signal, and based on the at least one auxiliary-path light signal, adaptively filtering an ambient light interference from the main-path light signal and obtaining an adaptive filtration result; or obtaining at least one auxiliary-path light signal transmitted by the same photoelectric transmitter and reflected back from a surface of skin without any artery underneath, and based on the auxiliary-path light signal, adaptively filtering a motion interference from the main-path light signal; then extracting a pulse signal from the adaptive filtration result. The present invention can simply and effectively eliminate the ambient light interference or motion interference upon photoelectric pulse signal measurement. Photoelectric type pulse signal measuring devices are also disclosed.
