This paper deals with the optical telemeter system in which data-transmission and power-supply through cylindrical surface of rotating spindle are realized. Data-transmission is carried out by means of one LED on the cylindrical surface of rotating head and enough numbers of PD facing to LED rotational locus. Non-contact powersupply is carried out by means of two pairs of coil and ferrite-core arranged on the rotating side and the stationary side respectively. These schemes through cylindrical surface are realized in a demonstration unit to clarify the effectiveness of the newly developed system. The measurement accuracy of the developed system is superior than 0.05°C for 0-50°C range from the view point of temperature change.
