| 1. | Be aware as well that these transforms are centered about the zero-frequency optical axis of the system .
还要记住这些变换式是以系统的光轴（频率为零）为中心的。 |
| 2. | Mathematical expression of included angle between optical axis and ray axis
光轴与光线轴夹角的数学表示 |
| 3. | The important thing to know that it has an axis of symmetry ? the optical axis
重点是知道主镜有一个对称轴? ?光轴。 |
| 4. | Reflecting prisms - optical axis , length of optical axis , axial section and optical parallelism
反射棱镜光轴光轴长度光轴截面与光学平行度 |
| 5. | The complex amplitude of cylindrical wave fields in the reference plan vertical to the optical axis
柱面光波场在垂直光轴方向的参考面上的复振幅表示 |
| 6. | Telecentric operation ( field rays leave parallel to optical axis , unlike barlow lenses which diverge rays )
远心手术（场射线离开平行光轴，不像巴卢镜片，其中发散射线） 。 |
| 7. | An algorithm for the resection of imagery along the optical axis is presented to implement both of the camera calibration and resection at the same time
摘要提出了一种沿主光轴方向影像的影像空间后方交会方法，实现了相机检校和空间后方交会的同时进行。 |
| 8. | " close - up performance of the summicron - m is on the same level as the performance at infinity setting ( actually infinity is that distance where the incoming light rays are parallel to the optical axis
近摄表现与无穷远时相当(事实上,无穷远处的光线是平行光轴入射的.对多数镜头而言,大约100倍焦距的物距时,入射光满足这一条件) |
| 9. | Like the primary mirror , the eyepiece has an optical axis , and this axis should be aimed at the center of the main mirror for best performance ? though in practice it is the center axis of the focuser drawtube that you aim at the primary mirror
目镜和主镜一样也有光轴，光轴应该对准主镜的中心? ?尽管实际上，目镜的光轴对准的是调焦筒（相当于调焦座）的中心。 |
| 10. | The director arrangement of the liquid crystal molecules in the cell is twisted . the director at the upper - substrate surface is set parallel to the optical axis of the polarizer and the director at the lower - substrate surface is set vertical to the substrate and the optical axis of the analyzer
A - htn型液晶盒中,液晶指向矢在上基板平行于偏振片的透光轴,在下基板上垂直于液晶盒表面,并且液晶盒内所用的液晶中掺有少量的手性剂。 |
