诸如ＸＹＺ微型定位器、转动光栅和ＣＤ－ＲＯＭ中的微聚焦透镜等的光机械部件都是许多光学系统必不可少的元件。ＸＹＺ微定位器用于对准光学系统；转动光栅和标准具用于改变可调谐激光器的波长；聚焦透镜总是运动的，目的是保持ＣＤ－ＲＯＭ的聚焦和跟踪。遗憾的是，普通...
Optomechanical components such as XYZ miniature positioners, rotating gratings and micro-focusing lenses in CD-ROMs are an essential element of many optical systems. The XYZ microlocator is used to align the optical system; the rotary grating and etalon are used to change the wavelength of the tunable laser; the focusing lens is always moving in order to maintain the focus and tracking of the CD-ROM. Unfortunately, ordinary ...
