摘　　要：提出用时间积分声光相关器进行长码的捕捉．以相加时间积分声光相关器为实验系统模型，把系统划分成光源部分、分束部分、扩束部分和光电检测部分，通过对各部分的分析和计算，建立了实验的最佳方案，并用该模型进行了时间积分声光相关器的实验，对实验结果进行了分析．首次在国内完成了时间积分声光实验模型，并给出了满意的实验结果．The time integrating acoustic optical correlator was used to capture long codes. The additive time integrating acoustic optical correlator was used as the experimental model. The experimental model was devided into four parts: light source, splitter, beam expansion and detector array parts . Through the analysis and calculation for each part, the optimum experimental model was established. The experiment of time integrating acoustic optical correlator was finished by use this experimental model, and the result was analyzed. It is the first time the experimental model of time integrating acoustic optical correlator was finished in our country and at the end of this paper, the satisfied experimental results in our laboratory were given.
