The new lens, which is thinner at the bottom than at the top, steers light to a viewer's eyes by switching light-emitting diodes along its bottom edge on and off.
这个新镜头，底部比顶部更薄，通过切换镜头底部边缘的发光二极管的开和关，控制进入到观众的眼睛的光线。
Just days after space shuttle astronauts repaired the Hubble space Telescope in mid December, the giant lens focused on a star cluster at the edge of the universe - and photographed heaven.
仅在航天飞机的宇航员于12月中旬修复哈勃太空望远镜几天之后，特大镜头聚焦于宇宙边缘的一个星团——拍摄到了天国。
In addition to maintaining idiosyncratic lens quality, the camera has a framing mask that lets you shoot square photos on 35-mm film-or even bleed the image to the edge like its old comrades.
除了保护特殊镜头的质量，这款照相机有一个限制框可以让你在35 mm的胶卷上拍正方形的照片——或者想它的老同志那样让画面周围有一圈暗角。
The end result is superb edge to edge resolution and high contrast in a low cost lens.
最终结果是极好的边缘到边缘的分辨率和低成本的镜头，高对比度。
Just days after space shuttle astronauts repaired the Hubble space Telescope in mid December, the giant lens focused on a star cluster at the edge of the universe - and photographed heaven!
仅仅几天后，空间站的宇航员在12月中旬修理哈勃太空望远镜，大镜头集中在一个星团在宇宙边缘-和拍照天堂！
This creates a softer edge for the lens flare.
这将创建一个柔软的镜头边缘光晕。
The lens is in the middle of the color, edge to be transparent, and by the local color and eye black eye of the same color, the same size, with very subtle.
镜片的中间是有颜色的，边沿为透明状，而由颜色的地方和眼睛的黑眼球一样的颜色，一样的大小，带上也非常的隐蔽。
From the usage characteristics of automatic testing optical lens, a viewpoint of straight-edge response function as final evaluation criterion is proposed in this paper.
从自动测量用光学镜头的使用特点出发，提出用其直边响应函数作为最终评价标准的观点。
There will be about 14" between the bottom edge of the image and the centerline of the lens."
将有大约14“之间的底部边缘的图像和镜头的中心线。
So far people have put forward some basic methods for evaluate the MTF values of the lens, such as knife-edge method, laser speckle method and extended frequency aperture (EFA) method.
迄今为止，人们已经提出了诸如刃边法、激光散斑法、扩展频率孔径法等多种测量离散成像器件MTF的方法。
