ABSTRACT:
Scanning and synchronizing light beams are deflected by a light deflector. The scanning light beam is used to scan an object surface, whereas the synchronizing light beam is applied to a grid for generating a synchronizing signal to detect the scanning position of the scanning light beam on the object surface. The grid includes a starting point control area, corresponding to a main scanning cycle starting position on the object surface, for modulating the synchronizing light beam applied to the grid so that light having passed through the starting point control area will have a different phase than the light from the other portion of the grid.
