摘要
本文提出了一种用四象限光探测器实时测量光盘动态特性的方法,测量了旋转光盘的起伏和倾斜,分析了测试结果及影响测量误差的各种因素。本方法具有实时、简单的特点。
By utilizing quadrant detectors, a dynamic testing methord for optical disk is proposed.The disk's height variation and tilt are measured under driven by the motors of disk driver. The analysis of the results is made with a brief discussion on the error in measurement.
