释义：

lens aperture 透镜孔径；透镜有效孔径；镜头光圈；镜头光圈刻度

例句：



Set to the desired lens aperture.

设置所需的镜头光圈。



The camera adjusts its focus, lens aperture, and shutter speed by itself.

它会调焦、调光圈和光闸速度。



Set the lens aperture to the aperture value designated by the flash unit according to the ISO setting your camera.

按照您相机上闪光装置ISO设置，设置好镜头的光圈大小。



A very small lens aperture is employed to correct spherical aberration , but this severely limits the final resolution.

可以用一个非常小的透镜孔阑来校正球差，但这会严重地影响最终鉴别率。



Another principle illustrated by Figure 4 is that any object having edges that line up with the edges of the lens aperture will tend to be resolved to some degree.

图四阐明的另一个原理是任何物体，只要它有边缘与镜头光圈边缘对齐，那么它的形状就能在一定程度上可以辨别。



Because maximum field of view in telecentric systems directly relates to the lens aperture closest to the object, larger front lenses are necessary for larger fields of view.

由于在远心系统中最大视场直接关系到镜头的镜头的光圈到物体之间的距离，若需要大的视场就必须要有大尺寸的前置镜头。



The paper discusses the difficulty presented in deducing Fourier transform formula due to the lens aperture restriction, and analyzes the desired conditions in using the formula in great detail.

本文讨论了薄透镜孔径对透镜傅里叶变换公式导出带来的困难，较全面地分析了使用该公式应满足的条件。
