摘要

ACT is the key components on the CD/DVD optical pickup, and is the precision servo- mechanism which can realize focusing and tracking of high-resolution ratio. Its characteristics (static & dynamic characteristics) is directly related with the quality of the CD/DVD optical pickup. This paper presents a new testing method & device for the characteristics of ACT based on VI & fiber optics sensors. The method & device can be used for testing the sensitivity (static characteristics) and frequency respond (dynamic characteristics) of ACT on the CD/DVD optical pickup.
