光线

As you know, wavefront systems project parallel rays of light into the eye and measure their displacement when they reflect back out.

光程差OPD 你知道，波前系统投射平行光线进入眼睛，并在这些光线反射回来的时候测量他们的位移。

A minus one diopter lens diverges parallel rays as if they were coming from a focal point at 1 m.

一度的负透镜可以使平行光线发散开来，仿佛这些光线发自于距透镜1 m 远的焦点。

Light rays leave the slit as a parallel beam .

光线通过小切口成为平行光线。

A tube containing a convex achromatic lens at one end and a slit at the other with the slit at the focus of the lens; light rays leave the slit as a parallel beam.

一端包含一个凸起的消色差透镜另一端在镜头的中心有一个小切口的小管；光线通过小切口成为平行光线。

Those rays which are near the axis are sometimes called paraxial rays.

近轴的那些光线有时叫作近轴光线。

We studied that the transfer matrix ABCD theorem for the passage of paraxial rays or the optical system possessing a rotational symmetry axis can be generalized for the skew rays propagated off-axis, whether the optical system possessing rotational symmetry axis or not.

本文推广了几何光学近轴光线传输的ABCD定理，使之适用于远离光轴的空间光线的传输，无论光学系统是旋转对称的还是非旋转对称的。

The study found that home and hospital phototherapy were equally safe and effective, but patients treated at home reported a significantly lower burden of treatment and greater satisfaction with treatment.

这项研究发现，家庭光线疗法和医院光线疗法一样地安全和有效，但是据家中接受治疗的患者报道，他们具有明显较低的治疗负担和对治疗更大的满意程度。

The computational flow of light propagation and the key techniques of visualization are presented. An optical system was employed to verify the correctness and feasibility of quaternion method in the calculation of beam propagation, and the pincushion distortion caused by the optical system was successfully simulated.

通过对某光学系统的仿真分析，成功仿真出图像经过光学系统产生的枕形畸变，证明四元数方法在光线传输运算中的正确性与可行性，为复杂光学系统的空间光线传输计算提供了另一种方法。

The light source directs rays through a plane convex lens that focuses the light into a parallel beam. The light beam passes through the grid diaphragm, which splits it to produce a second beam of light 90° out of phase.

光源将光线照射到平凸透镜上，透镜将光线聚焦成平行光束，光束穿过光栅膜片，光栅将光束分离出第二根90度异相光束。

Whether or series of Porro Roof Series, binoculars prism of this combination, its ultimate purpose is to do a series of light refraction, the final out of the light from the eyepiece for the formation of legislation is like.

不论是Porro系列或是Roof系列，望远镜的这一组合棱镜，其最终目的就是将光线做一连串的折射，让最后从目镜出去的光线形成为正立像。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
