Abstract(in English) A study of the non invasive measurement system, which is based on the Photothermal Spectroscopic technique for measuring physiological information on the human body was presented. First to improve the total SN ratio of the Photothermal Spectroscopic system, a new type detecting cell having a rotationally elliptic shape was developed. According to our experimental test, the SN ratio of the measurement system can be improved from -30dB to -48db, which is enough level to detect the PAS signal from the human body. Next in-vivo blood glucose level measurements by the PAS system were described. It is confirmed that there are good relationship between the In-vivo measurement results and those measured with commercial invasive blood glucose testers.
