宽带声光可调滤光器的设计——一种新型的换能器结构
The Design of Large Bandwidth Acousto-Optic Tunable Filter──A New Constitution of Transducer
【摘要】 在设计声增强型声光可调滤光器中 ,首次采用频带分段思想 ,提出梯形倾斜结构的换能器 ,获得了 50 MHz以上的工作带宽
【Abstract】 The idea of dividing bands is first used to design the piezoelectric transducer in acoustically enhanced type acousto optic tunable filter.A new transducer with gradient constitution is proposed.The operating bandwidth larger than 50MHz is obtained.
