PROBLEM TO BE SOLVED: To provide light measuring equipment for acquiring received light quantity information based on a cerebral site (measurement site) such as a cerebral bloodstream by removing any unnecessary received light quantity information based on a much more shallow scalp site such as a skin bloodstream from a scalp surface to a cerebral site (measurement site).SOLUTION: A probe for light transmission/reception is formed with two fixed holes with a second set distance. A light transmission path for light transmission connected to a light emission unit 2 is arranged in one fixed hole, and a light transmission path for light reception connected to a light detection unit 3 is arranged in the other fixed hole. A control unit 20 acquires the second received light quantity information of the rays of light from the light transmission path for light transmission of one probe for light transmission/reception to the light transmission path for light reception of one probe for light transmission/reception, and calculates received light quantity information by using the first received light quantity information and the second received light quantity information.COPYRIGHT: (C)2012,JPO&INPIT【課題】頭皮表面から脳部位(測定部位)までより浅い皮膚血流等の頭皮部位による不要な受光量情報を除去した脳血流等の脳部位(測定部位)による受光量情報を得ることができる光測定装置を提供することを目的とする。【解決手段】送受光用プローブには、2個の固定孔が第二設定距離をあけて形成されており、1個の固定孔には、発光部2と接続された送光用光伝送路が配置されるとともに、他の1個の固定孔には、光検出部3と接続された受光用光伝送路が配置され、制御部20は、一の送受光用プローブの送光用光伝送路から一の送受光用プローブの受光用光伝送路への光の第二受光量情報を取得して、第一受光量情報と第二受光量情報とを用いて、受光量情報を算出することを特徴とする。【選択図】図1
