간접광을 이용한 생체신호의 전송에 관한 연구

Abstract

The characteristics of the near infra-red lights were experimented to check the feasibility of telemetry using indirect transmitted light. The results of the experiments shows that the diffusely reflected light can be utilized as the carrier of biotelemetry even after several scattering and reflections.

An optical telemetry system using the indirect infra-red lights was developed. 3 channel ECG's are multiplexed in time domain and modulated into a PIM(pulse interval modulation) pulse sequence. The optical telemetry from a subject is carried out with the prototype system. A stable data acquisition was demonstrated.
