Abstract
An optical measurement device is provided with: a light source that irradiates, with light, a measurement object which has a fluid flowing thereinside; a light receiving unit which, upon receipt of scattered light from the measurement object irradiated with light, outputs a light reception signal according to the intensity of the scattered light; a disturbance generation unit which generates a disturbance signal for causing oscillation of a drive current to be supplied to the light source; and an adjustment unit which adjust the drive current on the basis of the result of a comparison between the disturbance signal and a signal generated on the basis of the light reception signal.
