PROBLEM TO BE SOLVED: To provide a biophotonic measurement device that has high safety (eye safety) to eyes of a person to be measured even when the intensity of measuring light is increased.SOLUTION: A scattered light measurement means 4 includes a receiver 9 that receives scattered light Ls guided by a scattered light-receiving means 8 and converts it into an electrical signal, and a measuring unit 10 that extracts and measures only the electrical signal by the scattered light Ls from the electrical signals converted by the receiver 9. The biophotonic measurement device also includes a measuring light controller 11b that controls the measuring light injection means 2 to lower the intensity of measuring light Lm or stops the injection of measuring light Lm when it is determined that an end of a measuring light irradiation means 7 is not in contact with a measured section 20 as the result of measuring the scattered light Ls by the measuring unit 10 of the scattered light measurement means 4.COPYRIGHT: (C)2012,JPO&INPIT【課題】測定光の光強度を強くしても、被測定者の目に対する安全性(アイセーフティ)が高い生体光測定装置を提供する。【解決手段】散乱光計測手段4は、散乱光受光手段8で導光された散乱光Lsを受信して電気信号に変換する受信部9と、受信部9で変換した電気信号から散乱光Lsによる電気信号のみを抽出して計測する計測部10と、を備え、散乱光計測手段4の計測部10で散乱光Lsを計測した結果、測定光照射手段7の終端が被測定部20に接触していないと判断されるとき、測定光Lmの光強度を低くするように測定光射出手段2を制御するか、あるいは測定光Lmの射出を停止する測定光制御部11bを備えたものである。【選択図】図1
