Patent abstract
An apparatus for angular positioning of a mirror includes a motor that rotates a mirror, a detector that detects a rotational angle of the mirror, and a controller. The controller supplies current to the motor so that the rotational angle of the mirror reaches a target angle, estimates, based on a model representing a relation between a value of current to be supplied to the motor and an angle of inclination of the mirror, the angle of inclination of the mirror to which current is supplied, and if the estimated angle exceeds a predetermined tolerance, adjusts the supply of current to the motor so that the angle of inclination of the mirror falls within the predetermined tolerance.
