Light scanning apparatus and method to prevent damage to an oscillation mirror, reducing its amplitude, in an abnormal control condition via a detection signal outputted to a controller even though the source still emits light
摘要：
A light scanning apparatus includes a deflector having an oscillation mirror that oscillates about an axis that is orthogonal to a main scanning direction. A detector detects a scanning light beam deflected by the oscillation mirror and moving in a scanning region. A controller adjusts the amplitude of the oscillation mirror based on a detection signal outputted from the detector, and stops driving the oscillation mirror when the detection signal is not outputted from the detector.
摘要（中）：

光扫描装置包括具有围绕与主扫描方向正交的轴振荡的振荡镜的偏转器。 检测器检测由振荡镜偏转并在扫描区域中移动的扫描光束。 控制器基于从检测器输出的检测信号来调整振荡镜的振幅，并且当检测信号未从检测器输出时停止驱动振荡镜。
