Abstract

An optical scanner includes a light receiving unit, a reference light irradiating unit, and a light-receiving-side correcting unit. The light receiving unit includes an optical phased array that implements scanning by a light beam by individually controlling phases of a plurality of branched lights using a scanning phase amount. The reference light irradiating unit generates reference light and irradiate the reference light onto the light receiving unit. The light-receiving-side correcting unit estimates a phase shift amount that occurs in the plurality of branched lights as a result of distortion of a substrate on which the light receiving unit is mounted from a detection result of the light receiving unit onto which the reference light is incident, and sets a phase adjustment amount to be applied to the plurality of branched lights such that the estimated phase shift amount decreases.
