The present invention provides an apparatus for angular positioning of a mirror, the apparatus including a motor configured to rotate a mirror, a detector configured to detect a rotational angle of the mirror, a controller configured to supply an electric current to the motor so that the rotational angle of the mirror reaches a target angle, to estimate, based on a model representing a relation between a value of the electric current to be supplied to the motor and a face tangle error angle of the mirror, a face tangle error angle of the mirror to which the electric current is supplied, and to, if the estimated angle exceeds a tolerance, perform a process of adjusting of a supply of the electric current to the motor so that the face tangle error angle of the mirror falls within the tolerance. |
