ABSTRACT:
A two-dimensional optical deflector includes a first deflector, which deflects a light beam about a first axis at a high speed, a second deflector, which deflects a light beam about a second axis perpendicular to the first axis at a low speed, and a fixing mechanism, which fixes the first deflector to the second deflector. The second deflector includes a rotation shaft capable of rocking about the second axis. The fixing mechanism includes a fixing member having a rotation shaft fixing hole, which engages with the rotation shaft with almost no space, and a fastener, which decreases the diameter of the rotation shaft fixing hole of the fixing member. The fixing member includes a first deflector mount surface. The first deflector is fixed to the fixing member so that a reflecting surface of the first deflector in a non-actuation state is almost parallel to the first deflector mount surface.
