Multipoint measurement system and method

A multipoint measurement method for performing optical measurements by transmitting light of a light source through a plurality of illuminating fibers to a sample so as to illuminate a plurality of points of the sample, collecting light of the light source and light beams including transmitted, reflected, scattered light beams at the plurality of points by a plurality of receiving fibers, and supplying the collected light beams to an optical measuring instrument, the multipoint measurement method comprising the steps of:

• a process for performing a base measurement for measuring light that is transmitted through the illuminating fibers and receiving fibers in a condition where there is no influence of a sample and performing a first monitoring of light of the light source;
• a process for performing a sample measurement carried out with a sample being placed for measuring light transmitted through the illuminating fibers, the sample, and the receiving fibers and performing a second monitoring of light of the light source;
• a process for obtaining an optical measurement value of the sample by dividing the quotient of an optical intensity obtained from the sample measurement with the sample being placed/an optical intensity of the light source obtained from the second monitoring by the quotient of an optical intensity obtained from the base measurement with no influence of a sample/an optical intensity of the light source obtained from the first monitoring;
• and
• a process for outputting the obtained optical measurement value of the sample.
