激光束光学系统的变焦理论

Zoom Theory of the Optical System for Laser Beam

从高斯光束经过光学系统的传输与变换规律出发，借助于高斯括号的性质，研究了激光束光学系统的变焦特性，导出了机械补偿式激光束变焦系统的变焦方程及补偿点位置方程，并给出了计算实例。

On the basis of the feature of Gaussinn beam propagation and transformation,thezoom feature of the optical system for laser beam is invotigated on the expansion of theGaussinn bracket. To the mechanically compensated zoom System for laser born,the zoom equation and the Compensation equation are derived. Finally,a practical example is given
