object beam

基本解釋

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、參考光地位對(duì)等的觀點(diǎn)來進(jìn)行分析，并給出了實(shí)驗(yàn)結(jié)果。
The results show that diffraction efficiency of a lossless grating increases with the higher ratio of reference beam width to object beam width.
對(duì)于無吸收的光柵，參考光束相對(duì)物光束越寬，衍射效率將越高。
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.
不過僅利用一對(duì)光束并不能得到有用的圖像，還需要從大約100個(gè)不同的角度讓物體光束掃描目標(biāo)。

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.
ECONOMIST: Microscopy
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).
