An optical measurement apparatus 1 includes a probe 3 having an irradiation fiber 5 that propagates light supplied from a base end 32 and irradiates the light from a leading end 33 and a plurality of light receiving fibers 7 and 8 that propagate light incident from leading ends 33 and output the light from base ends 32, a light source unit 22 that generates white light to be irradiated onto the body tissue and supplies the white light to the irradiation fiber 5, a measurement unit 24 that performs spectrometry for the returned light from the body tissue output from each of the light receiving fibers at a predetermined measurement timing, and a determining unit 27b that determines whether or not a measurement value measured by the measurement unit 24 is equal to or smaller than a predetermined threshold value, and causes the light source unit to perform a light emission process for obtaining a characteristic value of the body tissue for a predetermined time and causes the measurement unit 24 to perform a spectrometry process for obtaining a characteristic value of the body tissue if the measurement value measured by the measurement unit 24 is equal to or smaller than the predetermined threshold value. |
