Abstract
An optical deflector has a support. A movable plate is formed with a mirror for reflecting light from a light source. The mirror is formed on at least one surface of the movable plate. An elastic member couples the movable plate and the support to hold the movable plate in a deflectable manner. A driving coil is formed on at least one surface of the movable plate. A magnetic field producing means produces a magnetic field in a direction substantially parallel to the surface of the movable plate. The interaction between a current flow in the driving coil and a magnetic field produced by the magnetic field producing means causes elastic deformation of the elastic member, which, in turn, deflects the movable plate. A Hall element detects the deflection angle of deflection motion of the movable plate.
