路を備えた光式生体用テレメータ。[Claims for Utility Model Registration] On the transmitting side, an encoding unit that converts an input biological signal into a binary serial digital signal, and a carrier signal that generates a carrier signal with a higher frequency than the frequency components of surrounding optical noise. a modulation unit comprising a generation circuit and a switching circuit that receives the carrier signal as input and is turned on and off by the binary serial digital signal; and a modulation unit that emits light amplitude-modulated by the carrier signal supplied when the signal is turned on, and It is equipped with a light emitting part that occasionally interrupts light emission and a battery that supplies power to each of these parts, and a receiving side that receives the emitted light as an electrical signal and receives the frequency component of the optical noise mixed into this electrical signal. An optical biological telemeter comprising: a light receiving section having a filter for removing the light; and a detection circuit receiving the output signal of the light receiving section and restoring the binary serial digital signal.
