两种方光孔径声光器件的设计与性能比较

The Design and Performance Analysis of Two Types of Square Light Aperture AO Devices

采用最小二乘法简化优化参数过程，编制程序得到了对应不同的中心频率时超声跟踪反常ＴｅＯ２方光孔径声光器件的关键设计参数值，并与同类Ｈｇ２Ｃｌ２器件进行分析、比较，指出了它们各自的优越性．

The key design parameters of square light aperture, beam steering and birefringent TeO2 Acousto-Optical (AO) devices are obtained by computer program for different center acoustic frequencies, where the least square method is employed to simplify the design procedure. Its performances are compared with Hg2Cl2 devices and the advantages of both are analyzed respectively.
