Because of its unique advantages, using of infrared light telemetry as a research subject in the direction, the object of this telemetry system as a human pulse wave, and designing of a device. In this paper, it makes a detailed exposition about the theory of this telemetry system, explains the practical significance of the development of it, analysis of its existing problems and development trend. Considering that the measurement of pulse wave, especially infrared light telemetry system of it has the possibility, the urgency and the superiority in our country now. This text mainly gives a project about this telemetry device of the human pulse wave, and studies more for making it. That will lay a foundation and afford a feasible way for distance measurement with pulse wave, and it has considerable space and value of a wide range of applications. This device can collects a human pulse wave from the finger with the photoelectric sensor, and then transmitted as the infrared light by infrared light-emitting diodes. The receiver gets the signal with a distance, and outputted. At last, this text gives a comprehensive analysis and comparison of the actual situation of this device, includes the distance of the telemetry, the effect of the signal, the dispose of the disturb etc. Key words：pulse wav
