DSLR：数码单镜反光 (DSLR: Digital Single-Lens Reflex)

DSLR is an abbreviation of digital single-lens reflex. It alludes to a digital camera which with the sensor of digital imaging merges optics and mechanism of single-lens reflex camera. In the easier description, it is a digital single-lens camera that utilizes a mirror to conduct the light from the lens to the viewfinder. The viewfinder is used to preview the image before the user capture it, which is a hole, reclines on the back of the camera. Replaceable lenses are in-built in DSLR cameras. It allows a user to interchange lenses to get distinct views of any scene.

DSLR是数字单镜头反光的缩写 。它暗示了一种数码相机，它与数字成像传感器融合了光学和单镜头反光相机的机理。在更简单的描述中，它是一种数码单镜头相机，它利用镜子将光从镜头传输到取景器。取景器用于在用户捕获图像之前预览图像，该图像是一个Kong，斜倚在相机背面。可更换镜头内置在DSLR相机中。它允许用户更换镜头以获取任何场景的独特视角。

During the 2000s, DSLRs highly replaced film-based SLRs, and in the early 2010s, regardless of the rising acceptance of mirror less system cameras, DSLRs persists the most general type of interchangeable lens camera in use.

在2000年代，数码单反相机高度取代了基于胶片的单反相机，而在2010年代初，无论人们对无反光镜系统相机的接受程度如何，数码单反相机都坚持使用最通用的可互换镜头相机。

Willard S. Boyle and George E. Smith developed the first successful imaging technology using a digital sensor in 1969. In 2009, Boyle and Smith were awarded the Nobel Prize for Physics for their contribution to digital photography.

威拉德·博伊尔(Willard S. Boyle)和乔治·史密斯(George E. Smith)于1969年使用数字传感器开发了首个成功的成像技术。2009年，博伊尔和史密斯因其对数字摄影的贡献而被授予诺贝尔物理学奖。

In 1975, Steven Sasson the Kodak engineer developed the first digital still camera, which used a Fairchild 100×100 pixel Charge-Coupled Device.

1975年，柯达工程师Steven Sasson开发了第一台数码相机，该相机使用了Fairchild 100×100像素电荷耦合器件。

DSLR的工作 (Working of DSLR)

Through a medium of lens, light enters the camera and collides with the reflex mirror.
光通过镜头介质进入相机并与反射镜发生碰撞。
The reflex mirror throws back the light to the focusing screen in the vertically upward direction.
反射镜将光沿垂直向上的方向投射回对焦屏。
The passing of light happens through focusing screen and it enters the block of a glass which is a Pentaprism.
光线通过聚焦屏发生，并进入五棱镜的玻璃块。
Pentaprism directs the light towards different direction through two discrete mirrors then redirects it towards viewfinder.
五棱镜通过两个分立的镜将光指向不同的方向，然后将其重定向到取景器。
The viewfinder provides a user the live preview of the image.
取景器为用户提供图像的实时预览。
The reflex mirror overturns upward and obstructs the vertical path of light to keep it directed towards image sensor, when a user clicks the button to take an image.
当用户单击按钮拍摄图像时，反射镜会向上翻转并阻碍光的垂直路径，以保持其指向图像传感器的方向。
The light reaches the image sensor, when the shutter opens up.
快门打开时，光线到达图像传感器。
