1. The optical writing object lens of the laser direct writing device must be focused in spots by a focusing-servo mechanism. 在激光直接写入设备中需要有高分辨力的调焦伺服机构对光刻物镜进行调焦伺服。
2. The result indicated that the system lateral resolution were decided by the separation of optic-fiber bundle and the magnification of object lens. 结果表明光纤束的光纤间距与物镜的放大率决定了系统的横向分辨率。
3. The purpose of this study is to design a diffraction optical element using magnetorheological fluid for a switchable object lens used in optical pickup head. 本研究旨在探讨磁流变流体应用在绕射光学元件的设计与其应用于可变焦光学读取头的可行性。
