    Abstract: An electronic device includes a first optical transmitter, a second optical transmitter, a first optical receiver, and a second optical receiver. The first optical transmitter and the second optical transmitter may respectively transmit a first optical signal and a second optical signal with different wavelengths to a skin surface of a user. The first optical receiver may generate a first PPG signal based on a received first optical signal. The second optical receiver may generate a second PPG signal based on the received second optical signal. The second PPG signal may be used to determine a magnitude of noise in the first PPG signal.

    Abstract: A method can be used for controlling optical power. Output optical power of an optical source is monitored and it is determined whether a preset test control signal is received. When the preset test control signal is not received, a data signal is modulated to output light of the optical source and a bias current of the optical source is adjusted according to an output optical power monitoring result of the optical source to implement automatic power control. When the preset test control signal is received, a test is started and a test signal is superimposed to the data signal to form a superimposed signal. The superimposed signal is modulated to the output light of the optical source. The output optical power monitoring result of the optical source is ignored during the test period to maintain the bias current of the optical source at a preset target value.
