The analysis is made based on the reciprocity of object beam 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 object beam 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 object beam through the target about a hundred different ways.

不过仅利用一对光束并不能得到有用的图像，还需要从大约100个不同的角度让物体光束扫描目标。

This intense heat they project in a parallel beam against any object they choose, by means of a polished parabolic mirror of unknown composition, much as the mirror of a lighthouse projects a beam of light.

To do that requires scanning the object beam through the target about a hundred different ways.

When the reflected object beam and the reference beam are recombined, they create an interference pattern that encodes the 3-D image.

To create a hologram, such as those typically seen on credit cards, a laser beam is split into two (an object beam and a reference beam).
