| Abstract: | 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. |
