声光器件的全息功能分析

THE ANALYSIS OF HOLOGRAPHIC FUNCTION OF ACOUSTICOPTIC DEVICES

光学信息处理中，通常的声光调制器都是振幅型的．本文在正常声光互作用范围内，推出声光器件的相位调制关系并结合声光振幅调制，分析出声光器件所具有的全息功能．

In the optical information procession,the common acousticoptic modulators belong to the type of amplitude.In the field of normal acousticoptic interaction,this paper analyses the holographic function of acousticoptic device through the derived phase modulation relation of acousticoptic devices and acousticoptic amplitude modulation.
