The analysis is made based on the reciprocity of objectbeam with reference beam and experimental results are presented in this paper.
本文用物光、参考光地位对等的观点来进行分析,并给出了实验结果。

The results show that diffraction efficiency of a lossless grating increases with the higher ratio of reference beam width to objectbeam width.
对于无吸收的光栅,参考光束相对物光束越宽,衍射效率将越高。

A single pair of beams does not, however, produce a useful image. To do that requires scanning the objectbeam through the target about a hundred different ways.
