【Abstract】 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.更多还原
