摘要
对CCD记录的联合变换功率谱进行拉普拉斯算符运算和卷积运算的处理 ,并通过处理后的功率谱直接在计算机中进行傅里叶逆变换获得相关输出。计算机模拟和实验的识别结果均显示这种基于计算机处理的光电混合联合变换相关方法可以有效地抑制相关输出的自相关零级衍射斑 。
The joint power spectrum recorded by CCD is processed with the Laplacian and convolution operation,and the correlation results are directly obtained with the inverse Fourier transformation of the processed data in a computer.The computer simulation and the experimental results both show that the optic-electronic hybrid JTC based on computer processing can suppress the zero-order diffraction successfully and enhance the correlation peak remarkably.
