查询词典 Lens

The focus of the collimating lens has effects on the slope of the visual magnification curve while the focus of the imaging lens affects visual magnification of the whole moving range in the same way.

系统中视力板移动检测时，准直透镜焦距影响视觉放大率变化快慢，决定视觉放大率曲线的平缓程度；成像透镜焦距对视觉放大率产生整体影响，使视觉放大率曲线产生整体平移。

Let the lens dry, use your blower to blast away any remaining dust or particles, then cap the lens.

保持镜头干燥，使用吹风机吹掉剩余的其它灰尘或者微粒，然后盖好镜头。

In order to obtain the correct height reconstruction of a measured object through the traditional Fourier transform profilometry, the connecting-line between the exit pupil of the projecting lens and the entrance pupil of the imaging lens must be horizontal and set to parallel to the reference plane.

在拍摄过程中，采集完参考平面的光场后，只需要再采集一帧条纹图形，通过傅里叶变换、频谱滤波、逆傅里叶变换、相位展开等处理后就能得到物体的三维数据。采用传统的傅里叶变换轮廓术进行三维物体面型测量时，必需保证投影装置出射光瞳和成像装置入射光瞳的连线与参考面平行，并且它们的光轴应在同一平面上，才能得到较为准确的测量结果。

We focus on resolving the following problems in FTP, that is how to guarantee the measurement accuracy of FTP when the connect line between the exit pupil of the projecting lens and that of the entrance pupil of the imaging lens is not parallel to the reference, or the two pupils are not coplanar, or neither the connect line parallel to the reference nor the two pupils coplanar.

推导出了适用范围更广泛的变形条纹描述公式和相位计算方法以及相位—高度映射算法。对于传统的傅里叶变换轮廓术测量系统而言，由于要求投影仪出瞳与摄像机入瞳连线与参考面平行，而且要求投影仪光轴与摄像机光轴共面，所以它可以被看作是本文所提出系统结构在该种情况下的一种特例。

In our study, we first designed the high and low-degree lens according to the real diopters of guinea pigs, and explored the sensitivity of guinea pigs to lens-induction.

本研究中，我们首次根据豚鼠眼的实际屈光度数设计不同高低度数的诱导透镜，观察豚鼠眼对透镜诱导的敏感性。

Accordingly, undertook improvement to measurement technique and unit of feet lens group, rear sight the design is staff guage of 0.02mm mobile vertical for the least scale division value, telescopic design is collimation binoculars, face of lens of feed rod lever is 1.2362m above to rear sight distance.

因此，对测量方法和尺镜组装置进行了改进，将标尺设计为最小分度值为0.02mm移动铅直标尺，望远镜设计为准直望远镜，光杠杆镜面到标尺距离为1.2362m以上。

METHODS The pollu-tive status of Acanthamoeba of drinking water and cornea contact lens preservation box and preserved liquid of college students in Yanji were studied.103drinking water samples and93cornea contact lens preserved liquid and the cleaning liquid were inoculated on the surface of non-nutrient agar plates that contained heat-killed E.coli.
