    Abstract: In an optical measurement system and imaging method adapted to measure in vivo information in a living body without harming the living body, light rays of a plurality of wavelengths which are modulated in intensity with a plurality of different frequencies are irradiated on a plurality of irradiation positions on the surface of a living body, and time-variable changes in living body transmitting light intensity levels corresponding to the respective wavelengths and the respective irradiation positions are measured at different positions on the surface of the living body. Light is utilized to image the results of the measurements, in which the measuring time is shortened by estimating fluctuation attributable to the living body, and the presence or absence of a change in measured signal can be decided easily by displaying an estimation signal and a measured signal at a time.

    Abstract: A light emission section includes light generators which are operated on the basis of drive signals from a controller so as to emit near infrared interferable light beams having different specific wavelengths to a light interference section. The light interference section includes a beam splitter having a low-reflection region. The beam splitter allows a most portion of the near infrared interferable light beams to propagate toward an object to be examined, and reflects a portion of the near infrared interferable light beams to a movable mirror. The beam splitter causes interference between measurement light reflected by the object and reference light reflected by the movable mirror, and the resultant interference light propagates to a light detection section. The light detection section receives the interference light and calculates predetermined information regarding the object by making use of the quantity distribution of the interference light. A display section displays the calculated information.

    Abstract: Light rays of a plurality of wavelengths which are modulated in intensity with a plurality of different frequencies are irradiated on a plurality of irradiation positions on the surface of a living body, and time-variable changes in living body transmitting light intensity levels corresponding to the respective wavelengths and the respective irradiation positions are measured at different positions on the surface of the living body.

In living body optical measurement system and method, the measuring time is shortened by estimating fluctuation attributable to the living body, the presence or absence of a change in measured signal can be decided easily by displaying an estimation signal and a measured signal at a time, and a local change in hemodynamic movement can be measured by detecting light rays transmitting through the interior of the living body by means of two means for light detection disposed at different two sites (equidistant from the light incident point) on a subject and by separating only the local change in hemodynamic movement from an overall change in hemodynamic movement in the living body in accordance with a logarithmic difference between the two detection signals.
