查询词典 angular aperture

Meanwhile, the optical path difference and the degree of modulation of this kind of interferometer are calculated. It′s easy to be found that, in order to get the better diagram of the degree of modulation, both the inclination of the two image planes and the image aperture angle must be small angles, and both the lateral and longitudinal offsets must be smaller.

可以看出：要得到较好的调制图形，必须满足两像面夹角和像方孔径角都是小角的条件，且两个像点之间的横向距离和纵向距离越小越好。

The aperture is the actual opening that allows light into the optical bench of the scanner.

光圈是实际的开放，让光进入光替补的扫描器。

As it communicates, the numerical value of the aperture of the projection optical system scanner composes 1,30 maximum value on the branch as a whole.

因为它传达的数值孔径投影光学系统的扫描仪构成1，30 最大的价值的分支机构作为一个整体。

Paraboloid antenna and high efficiency feed aperture.

抛物面天线及高效率喇叭。

The half paraboloidal IRA is easy to match UWB pulse generator. The principle and radiation field of IRA is discussed with field on the spherical surface aperture.

抛物面冲击脉冲辐射天线是一种新概念的超宽带电磁脉冲辐射天线，它包括抛物面反射器、TEM馈臂和匹配电路等，半抛物面冲击脉冲辐射天线解决了与源的匹配和连接问题。

With high precision linear CCD as measuring sensor and combining with a mechanical scanning method,a quick measurement for the aperture of wire drawing die is carried out by the parallel light projection method.

采用平行光投影法，以高精度线阵 CCD为测量传感器，结合机械扫描方法，完成对拉丝模孔径的快速检测。

The relationship between wavelength and numerical aperture is valid only for increased resolving power when light rays are parallel.

当光线是平行时，波长与 numerical aperture 的相关性在增加解析度时才会有效。

Hence only parallel rays are able to pass through this aperture and therefore as the reflecting object seems to be infinitely remote, there can be no perspective distortion and also magnification is independent of the distance to the lens.

因此，只有平行光线能够通过此孔径，因此，作为反映的对象，似乎是无限遥远，不可能有任何角度的扭曲和放大，也独立于距离镜头。

This aperture formed a sort of peep-hole.

这个洞眼正好是个贼眼。
