OPTICAL MEASUREMENT APPARATUS

摘要

An optical measurement apparatus according to the present invention includes: an irradiation fiber; a plurality of light receiving fibers; a light source unit that generates and outputs light to irradiate a biological tissue and supplies the light to the irradiation fiber; a measurement unit that has a plurality of measurement units and performs spectrometry on each returned light from the biological tissue, the returned light output by each of the light receiving fibers; and a control unit that causes a predetermined storage unit to store a measurement result by the measurement unit: and the control unit causes the storage unit to store a measurement result after each measurement unit starts measurement for characteristic value obtainment, the measurement result being data necessary to obtain a characteristic value of the biological tissue.

1. An optical measurement apparatus that performs spectrometry on returned light reflected or scattered by a biological tissue and obtains a characteristic value of the biological tissue, the optical measurement apparatus comprising:
an irradiation fiber that conducts light supplied from a proximal end thereof and irradiates the light from a distal end thereof; a plurality of light receiving fibers that each conduct light entering from a distal end thereof and outputs the light from a proximal end thereof; a light source unit that generates and outputs light to irradiate the biological tissue and supplies the light to the irradiation fiber; a plurality of measurement units that are provided as many as the plurality of light receiving fibers and respectively perform spectrometry on returned light from the biological tissue, the returned light respectively output by the plurality of light receiving fibers; and a control unit that causes a predetermined storage unit to store each measurement result from the plurality of measurement units, wherein the plurality of measurement units include at least a first measurement unit and a second measurement unit, the first measurement unit has a first measurement device and a first determination unit, the second measurement unit has a second measurement device and a second determination unit, the first measurement device and the second measurement device receives the same returned light, when the first determination unit detects a received light intensity greater than a threshold, the first measurement device starts spectrometry for characteristic value obtainment, when the second determination unit detects a received light intensity greater than a threshold, the second measurement device starts spectrometry for characteristic value obtainment, thereby synchronizing timing in which measurement for characteristic value obtainment by each of the measurement units is started, and the control unit causes the storage unit to store a measurement result after each measurement unit starts the measurement for characteristic value obtainment, the measurement result being data necessary to obtain the characteristic value of the biological tissue.
