【摘要】：為避免傅里葉望遠鏡重建圖像壓縮變形,依據(jù)激光發(fā)射孔徑間距,提出了重建圖像時矩陣行、列數(shù)間應(yīng)滿足的關(guān)系;為評價仿真或?qū)嶒灥某上裥Ч?依據(jù)發(fā)射孔徑間距和原目標圖像矩陣大小,確定重建圖像矩陣規(guī)模的具體大小。嚴格推導(dǎo)逆離散傅里葉變換在傅里葉望遠鏡中實現(xiàn)圖像重建的過程,分析了其中所隱含的發(fā)射孔徑間距和重建圖像矩陣規(guī)模間的數(shù)量關(guān)系,得出兩個限定關(guān)系公式。仿真和實驗結(jié)果表明這兩個公式可分別保證圖像輪廓不產(chǎn)生畸變、重建目標矩陣與原始目標矩陣規(guī)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.
