BIOLOGICAL LIGHT MEASUREMENT DEVICE, BIOLOGICAL LIGHT MEASUREMENT METHOD, AND ENGAGEMENT MEMBER FOR MOBILE POSITION SENSOR

摘要

This biological light measurement device includes: a light irradiation and measurement unit for irradiating a subject with light and measuring light transmitted through the subject; a signal processing unit for processing measurement data of the light irradiation and measurement unit and generating a biological light measurement image; and a position measurement unit for measuring a position at which the light irradiation and measurement unit irradiates the subject with light and a position at which the transmitted light from the subject is extracted. The light irradiation and measurement unit is provided with a plurality of optical fibers, a plurality of optical fiber plugs attached respectively to the plurality of optical fibers, and a holder for holding the plurality of optical fiber plugs, the holder being detachably fixed to a measurement site of the subject. The position measurement unit is provided with a mobile position sensor, and an engagement member attached to the mobile position sensor and shaped to detachably engage with the plurality of optical fiber plugs held by the holder.
