平面束

One slightly concave cylindrical lens combination is used to change one laser beam into small sector in small angle, and one reflector projects the laser beam to prism driven by a motor to rotate in high speed to produce one reciprocating and scanning small sector plane.

采用微凹柱面透镜组将激光光源发射的一束激光拉成具有微小夹角的小扇面，利用反射镜将此激光束透射到由电机驱动的高速旋转多面棱体上，使激光束产生一个小扇形往复激光扫描光平面。

The bundles are superimposed in several planes and interlace with one another in three planes: longitudinal , vertical and horizontal

纤维束则以各种不同的方向，从三个平面互相交织，有纵走的，垂直的及平行的。

For easy to install and checkout optical instrument,here primarily introduces the basic principles and structure component of collimator,which is composed of object lens、divisional board and ground glass.

1引言根据几何光学原理，无限远处的物体经过透镜后将成像在焦平面上；反之，从透镜焦平面上发出的光线经透镜后将成为一束平行光。

This surface works a bit like a giant radio telescope dish in reverse: Rather than focusing parallel astronomical light rays to a point, it collects the scattered plasmons emerging from a tiny sample--positioned strategically near the mirror--and redirects them into a plasmon "beam" in the metallic plane.

这个表面的工作原理相当于一个倒置的巨型射电望远镜的盘面，不同于天文望远镜把平行的天体光线会聚到一点，这一设计起到的作用是收集从一个位置恰好位于像点的微小样品散射出来的等离激元，并把他们重定向成金属平面上的一个等离激元束。

Microscopic stress state after compression in the direction perpendicular to woven plane and fiber yarns is analyzed in detail.

Ability of a substance to rotate the plane of polarization of a beam of light passed through it, either as crystals or in solution .

物质使一束穿过它的光线的偏振平面发生旋转的能力，一如在晶体或溶液中。

According to the invention, the damping device consists of a plurality of separate individual dampers which are arranged with their elastomer and intermediate layers in the direction of the main bending plane of the support beam.

据发明，减振装置构成的多元化的单独的个人阻尼器，其中安排与他们的弹性体和中间层的方向，主要弯曲平面的支持束。

The grating of plane change distance is applied to break the white light into monochromic light at the 3W1B in the BSRF,and obtain a good monochromic light source of good energy resolution,high intensity,broad energy spectrum.

在北京同步辐射源的3W1B束线上，利用平面变间距光栅分光，获得单色性较好，强度较高，能谱连续可调的单色光源。

The plane-parallel resonant cavity is built up in theory with the U-shaped bending waveguide for TM mode. The beam splitting and convergence effect are also discussed for the structure composed of filling-factor graded wave-like 2D-PC and one-dimensional multilayer thin films.

利用TM模的U型转弯波导构建了新型的平行平面谐振腔，并指出由填充率渐变型波状结构二维光子晶体和一维多层薄膜构成的混合结构在光分束和抑制光束发散方面的作用及其在平行平面谐振腔中的潜在应用。

As the pulsar rotates, this beam sweeps the sky in the same way that a lighthouse beam sweeps around the horizon

当脉冲量旋转时，辐射束扫过天空，就像灯塔的光束绕地平面扫视那样。
