A lithium niobate anisotropic acousto-electro-optic spectrum analysor with central frequency 60 MHz was made. Its central frequency can be changed from 50 MHz to 70 MHz and its bandwidth can be increase from 26 MHz to 37 MHz.

• 用LiNbO3制作了一个60MHz的反常声电光频谱分析器件，测试结果表明，器件中心频率可以由50MHz变到70MHz，频带宽度由原来的26MHz扩大到37MHz。
