摘要： An optical scanning device includes a pre-deflection optical system including a first optical element that adjusts the shape of beams emitted from the light source; and a second and third optical elements arranged such that the second optical element is arranged closer to the light source than the third optical element is. Both of the second and third optical elements have no refracting power in the deflection scanning direction and have positive refracting power only in a direction perpendicular to the deflection scanning direction. An interval between scanning lines formed on the scanned area and a deviation of the scanning-line interval between scanning positions are adjusted by displacement of the second and third optical elements in a direction of an optical axis of the pre-deflection optical system and displacement of at least one of the second and third optical elements in the direction perpendicular to the deflection scanning direction.

摘要： A light source system includes a splitter that split light beams F0 emitted from a light source into at least light beams FM and light beams FS, and an optical detecting system that guides the light beams FM to a detector. A light component near a light-intensity peak of the light beams F0 in a plane perpendicular to a propagation direction of the light beams F0 is included only in the light beams FS. Accordingly, light beams have a substantially circular or elliptic cross section with the intensity peak near the center. Light at the peak is supplied to the outside, and other light is used to control an amount of light.
