声光偏转器的调制传递特性
Modulation transfer characteristics of an acousto-optic deflector
摘要
利用调制传递函数(MTF)分析了声光偏转器的分辨率。建立了高斯光瞳函数与声光偏转器的调制传递函数间的关系。适当选择声光介质与高斯光束(1/e~2振幅附近)的截断比可以增加分辨点数。
Abstract
The resolution of the acousto-optic deflector is analyzed by means of modulation transfer functions. The relation between the modulation transfer functions of acousto-optic def lector and Gaussian pupil is established. The resolution can be increased by properly selecting the truncation ratios of acousto-optic media and Gaussian beam (nearly 1/e2 beam width).
