In dvd focus servo system, the warp of the disc induces periodic disturbance whose frequency is same as the rotation frequency of the disc
摘要在dvd聚焦伺服系統中,光盤翹曲會導致產生與光盤轉動頻率相同的周期性擾動。The aim of defocus detection is to achieve high etching quality by providing the defocus error signal for focus - servo system which can make the etching spot focus accurately
離焦檢測的任務是為聚焦伺服系統提供聚焦誤差信號,使寫入光斑能夠精確聚焦,從而保證刻蝕質量。The output of this correction signal can be used to drive a simple auto - focus servo. a typical example of such a servo is illustrated below
修正信號的輸出可以用於驅動一個簡單的自動聚焦伺服器。下圖為一個自動聚焦伺服器的示意圖。The servo system is responsible for the focusing and tracking of the laser beam on the cd
伺服系統負責激光束在光盤上的聚焦和軌道跟蹤。分享友人
