Optical switch based on MOEMS technology obviously has more advantages than optical switch base on other technologies, such as wavelength transparence and polarize independence.
基于MOEMS技术的光开关和其他技术类型的光开关相比显然具有更多的优良性能，例如波长透明和偏振无关等。
Using the transparence CD, PSD can detect the displacement of laser spot between non-placing and placing the CD, and it can be used to calculate the parallelism between optical head and spindle motor.
考虑在主轴上放置透明盘片，用PSD测量位移子系统测出放置透明盘片前后的光斑移动距离，就可以计算出光头与主轴马达间的平行度。
