摘要
介绍了付里叶光学分析的基本原理,并将其应用于声光信号处理系统。分析了付里叶光学分析方法对于复相关运算具有的独特的方便性、对于空间及时间积分的两类声光处理系统,导出了复透射率的表达式。分析结果表明:采用付里叶光学分析声光信号处理系统是可行的,并对实践具有重要的指导意义。
The basic principle of Fourier optics analyzation and its usage in the acousto-optic signal processing system are introduced.The specific convenience of Fourier optics analyzation method in complex correlation calculation is discussed.The expressions of complex transmitting function of two kinds of acousto-optic signal processing systems(spatial integrating and time integrating correlator) are deduced.The analysis result shows-it is convenient using Foruier optics to analyze acousto-optic signal processing systems and is of important value to instruct practice.
