| 摘 要： | 论述了空间积分声光相关器对脉冲调制连续波信号的瞬时响应，分析了从实时光电检测器中检测出的波形，该波形是脉冲宽度，加权函数参量和与脉冲位置相关的空间衍射光分布的函数。进一步提出了脉冲序列相关时的光分布关系并通过实验加以论证。

| Abstract: | The temporal response of a space integrating acousto optic correlator to pulse modulated cw signals is described.The detected waveforms from a real time photo diode detector are analyzed as a function of pulse width,weighting function parameters,and relative spatial distribution of diffracted light to pulse position.The relative spatial distribution of the diffracted light to the correlation of pulse sequences is further proposed,and proved by the experimental results. |
