    • A disclosed optical scanning device includes a light source unit configured to emit a laser beam; an oscillating mirror configured to deflect the laser beam from the light source unit; a scanning/imaging optical system configured to focus the deflected laser beam on a target surface; and plural light-receiving elements configured to receive the laser beam in a scanning area of the laser beam, the position of the oscillating mirror being adjusted such that time intervals between output pulses in output signals of the respective light-receiving elements become substantially the same between the light-receiving elements and/or widths of the output pulses become substantially the same between the light-receiving elements.
    • 所公开的光学扫描装置包括被配置为发射激光束的光源单元; 配置为使来自所述光源单元的激光束偏转的振荡镜; 扫描/成像光学系统,被配置为将偏转的激光束聚焦在目标表面上; 以及多个光接收元件,被配置为在激光束的扫描区域中接收激光束,调节振荡镜的位置,使得各个光接收元件的输出信号中的输出脉冲之间的时间间隔变得基本相同 光接收元件之间和/或输出脉冲宽度在光接收元件之间变得基本相同。
