Convergent Beam Propagation in Simulative Cylindrical Bio-tissue;
会聚光在柱状模拟生物组织中的实验研究
For detecting wavefronts from the system with long optical path or multi-component lens with one by one aligning,the phase-shifting lateral shearing interferometry of convergent beam with the convergent beam as light source for interferometry is proposed,which is based on Michelson interferometer.
为了检测长光程情况或多组分光学镜头逐片装校中的波面,提出一种以会聚光波直接作为干涉测试光源的会聚光移相剪切干涉方法,阐述了基于迈克耳孙干涉仪原理的会聚光横向剪切干涉光路,建立了会聚光横向剪切波面的数学表达式,并与一般横向剪切干涉相比较,分析了剪切量和波面偏移量的特征,且引入移相干涉技术求取剪切波面。
"A convex lens causes rays to converge on a single point, the focal point."
会聚透镜使光线会聚于一点,即焦点。
In this case the rays obviously do not converge.
此时，光线显然不会聚。
focused light rays can set something afire.
聚焦的光线会让东西烧起来。

Notice that in all cases, the rays either diverge from or converge toward the foci.
注意在所有的情况下，光线不是从焦点发散就是会聚到焦点。

When viewed using a bright lamp, the beams of light can be seen as spectra of colors.
在明亮的聚光灯光源下，光束会还原为光谱色彩。
Since these rays do not actually meet, they cannot form an image without a condensing lens of sort.
由于这些光线实际上不相交，如果不用某种会聚透镜的话，它们是不能成像的。
