摘要
电子信息装备越来越需要具有大时间带宽积的处理能力,以应对实战环境情况下复杂电子信号的侦察。声光调制技术有随空间-频率线性变化、以及驱动信号特征的光栅调制两个基本特性。第二个特性使得利用声光器件完成复杂光信息处理成为可能。据此,按数学模型分析了两种声光相关运算的光路结构,根据这两种结构完成了相应的试验测试,并得到相应的测试结果。
Acousto-Optic modulator belongs to spatial light modulator, and behaves two kind of characteristics what space-frequency change linearly and the driven signal modulate by grating. The second characteristic is basic about optical information processing. According to this characteristic, the paper analyses two mathematic models of different optic correlation configurations. Furthermore, we finished the experiments and got relevant testing results and figures.
