晶体锥光效应控制激光束方向的研究
|
摘要
控制激光束在空间上改变的方式主要有声光偏转和机械偏转，声光偏转的驱动系统复杂，色散严重；机械偏转响应慢，偏转速度与控制精度相互制约。为此，根据晶体锥光效应提出一种新的光偏转方法，在双轴晶体中光波矢沿光轴方向入射时，其传播方向随光偏振态的不同而改变，光的偏振态可以通过控制法拉第旋转器上磁场强度改变，这样实现对激光束方向的控制。论文重点介绍了晶体锥光效应应用在光盘寻迹上的方案，对法拉第旋转器、双轴晶体、光学透镜等主要光学元件进行详细分析，分析该方案光头寻迹特点、跟踪速度指标以及光头结构，并与传统机电跟踪寻迹方式进行对比。同时，对光束控制在光开关、线性扫描等方面的应用做了相应的研究，此技术有广阔的应用前景。
There are two main transferring ways of controlling Laser beam in space: acousto-optic deflexion and mechanism deflexion, the driving system of acousto-optic deflexion is complex and the dispersion is serious. The response of mechanism deflexion is slowly, which velocity and precision are confinement each other. Therefore, based on conical effect in crystal a new method of light deflexion is putted forward. The wave vector of light transmitting along the light axis of biaxial crystal, the direction of light will vary with the polarization states which can be changed by controlling the magnetic field of Faraday rotator. So controlling direction of Laser beam comes true. A scheme that conical light effect is applied to tracking of CD is introduced. These optical elements such as Faraday rotator 、 biaxial crystal and optic lens etc have been analyzed. Characters of Optic Headed 、 the index of tracking velocity and the structure of Optic Headed have been analyzed and compared with traditional tracking means of machine-eletricity .In the meantime, the application of optical switch and linearity scanning have been discussed in this paper.
