后焦面 meaning in Chinese
back focal plane
rear focus surface
Examples
- At the position of the zeroth order , all wavelengths from each slit add constructively ; this produces the bright white light you see as the zeroth order at the center of the back focal plane of the objective ( figures 3 and 4 )
在零级位，从栅格标本的各个窄缝中发出的所有波长会产生相加的干涉，在物镜的后焦面中心会看到明亮的白色像。 - At the back focal plane of the objective , the blue wavelengths from each slit interfere constructively to produce the blue area of the diffracted image of each spectrum or order ; similarly for the red and green areas ( figure 4 ( a ) )
在物镜的后焦面，从各个窄缝发出的蓝色波长光产生增强干涉而产生各级的衍射图像的蓝色区域，红色波长和绿色波长也一样(图4 ( a ) ) 。 - If you were to block out the outermost diffracted orders by placing an opaque mask at the rear of the objective , you could reduce the resolution of the lines of the grating , or any other detailed object , or " destroy " the resolution altogether so that the specimen would not be visible
假如用不透明的遮挡物在物镜后焦面挡住外圈衍射级的光线，线形栅格图像的分辨率将下降，这样完全地破坏了分辨率，标本的细节就无法看见。 - The light route used by measuring instrument determined its volume , according to the place between sampling area and lens , with the application background limits , the miniature atomized particles size measuring instrument takes scheme that the sampling area locate in front of the lens and the optic - electronic sensor at the back focal plane of the lens . the miniature atomized particle size measuring instrument employs
测量仪器采用的光路直接影响仪器的结构尺寸，接收透镜和采样区位置的关系具有不同的配置方案，由于雾粒粒径测量仪应用背景的限制，所采用的光路配置方案是被测颗粒位于透镜前方，光能接收器件位于透镜后焦面上。
