【摘要】：为避免傅里叶望远镜重建图像压缩变形,依据激光发射孔径间距,提出了重建图像时矩阵行、列数间应满足的关系;为评价仿真或实验的成像效果,依据发射孔径间距和原目标图像矩阵大小,确定重建图像矩阵规模的具体大小。严格推导逆离散傅里叶变换在傅里叶望远镜中实现图像重建的过程,分析了其中所隐含的发射孔径间距和重建图像矩阵规模间的数量关系,得出两个限定关系公式。仿真和实验结果表明这两个公式可分别保证图像轮廓不产生畸变、重建目标矩阵与原始目标矩阵规模相同。
[Abstract]:In order to avoid the compression deformation of reconstructed image by Fourier Telescope, according to the distance between laser emission aperture, the relationship between the rows and columns of the reconstructed image is put forward, in order to evaluate the imaging effect of simulation or experiment, The size of the reconstructed image matrix is determined according to the distance between the transmit aperture and the size of the original target image matrix. The process of image reconstruction by inverse discrete Fourier transform in Fourier telescope is derived strictly. The quantitative relationship between the distance of emission aperture and the size of the reconstructed image matrix is analyzed and two limited relation formulas are obtained. The simulation and experimental results show that the two formulas can ensure that the image contour is not distorted and the reconstructed target matrix is the same as the original target matrix.
