查询词典 spatial

This technique uses a spiral phase plate with a small central aperture placed on the Fourier plane of so imaging system. If the spiral phase filter is rotated by a certain angle around its central axis, a phase shift between the zero-order spatial frequency component and the remaining of the object is produced, and the magnitude of this phase shift is proportional to the rotation angle. Using this property, we can record a sequence of intensity distribution of the output beams corresponding to different rotation angles, and then digitally reconstruct the objects by using a phase-shifting algorithm. Both the theoretical analysis and simulation experiment results demonstrate the feasibility of this approach.

在成像系统的频谱面上放置中心带有一通光孔径的螺旋相位板，在输出面上记录输入物体经螺旋相位滤波后的输出像；将螺旋相位滤波器绕轴旋转一定角度，通过中心光孔的零频成份与其他高频成份间会产生与旋转角度成正比的相移；利用这一特点，通过记录多幅对应不同旋转角度的输出光场强度分布图，然后再用一定的相移算法实现被记录物体相位分布的数字再现。

Research about China must study her control approach, because in human history, you cannot find another one like Chinese culture, which has been entirely controlling the citizen抯 life not only in political and conscious level, but also the substantial and spatial realm coving from macro-scale urban planning, through the traditional architectural construction regulation, to every sophisticated detail of daily life since thousands of years ago.

研究中国必须要研究其控制方式。因为历史上恐怕再难找到像中国文化这样，在几千年中如此事无巨细地讲究控制，不仅是在政策和意识形态上，并且也是物质化和空间化的：从城市规划的宏观规则，建造营造的中观法式，到生活用品的每一个微观细节。
