Abstract

A controller of an optical measurement apparatus causes, in a condition that a rotational speed of a rotary body is controlled so that the speed is a specified value, a light source to generate light having a constant intensity and apply the light to an irradiation region, and acquires first timing information based on a change with time of an intensity of reflected light or transmitted light that is output from a second detection unit receiving the reflected light or transmitted light of the applied light. The controller causes the light source to periodically generate pulsed light in accordance with the first timing information and apply the pulsed light to the irradiation region, and acquires second timing information based on a result which is output from the first detection unit whose measurement is periodically enabled in accordance with the first timing information.
