Abstract:
1. A biological optical measurement instrument comprising: a measurement probe attachable to an external surface of a subject, which irradiates light beams having a plurality of wavelengths from a light beam source through optical fibers onto a subject, and collects the light beams passed inside the subject from a plurality of positions, and produces from collected light beams a light beam intensity picture image of the subject, wherein the measurement probe is provided with a plurality of optical fiber fixing members insertable through a plurality of access entries, which fix ones of the optical fibers in a predetermined interval and a support member which supports the optical fiber fixing members, and where at least one optical fiber fixing member of the plurality of optical fiber fixing members is a hollow holder having a hair displacement access cut out portion which is different than the access entries, extending along a side thereof for at least a partial longitudinal length thereof, for displacing portions of hair of the subject outside of a hollow area of the hollow holder.
