object beam造句

In order to investigate the phenomenon that holograms tend to be deteriorated on baing recorded in photopolymers with shrinkage , a fourier hologram is taken with slant gratings formed by the reference beam and object beams of different space - frequency
摘要为了分析光致聚合材料记录的谱面全息图在再现过程中发生“擦除”现象，将谱面全息图看作由不同角谱的物光与参考光在光致聚合材料内形成的不同倾斜角度的光栅总和。
The experiment results show that there are optimal defocus distance and exposure for the given system and recording material , and to obtain the best snr different reference - to - object beam ratios are also needed for black - white digital images of different space frequencies
实验结果表明，对于给定的系统及记录介质存在一定的最佳离焦量和曝光量，而对于不同空间频率的黑白二值条纹图像还需要采用不同参?物光比以最终获得最佳的信噪比。
