| 摘 要： | 本文详细分析了运动物体的线阵扫描全息术。其重建象和静止物体的重建象相比,将有伸缩、旋转及位移等变化,而且在x、y二个维度上其成象位置也不同。这些畸变取决于物体运动速度与扫描速度之比值。适当地提高扫描速度可减小畸变。如果对物体运动有某些了解,也可根据成象规律予以校正。文中还给出了实验结果。

| Abstract: | The holographic imaging of moving object using linear array by scanning is analysed-Comparing moving object with stationary object, its reconstructed image is spreaded, pressed, rotated and shifted. Its distsnce in X and Y dimensions are different. The distortion depands-on the ratio between the object speed and the scanning speed. It can be reduced through increasing the ratio and it can also be corrected if the motion is known. The experimental result is given. |
