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。

单反相机的组成 (Components of DSLR Camera)

Following are the main components of a DSLR camera,

以下是DSLR相机的主要组件，

• Lens

  镜片

• Reflex mirror

  反光镜

• Shutter

  快门

• Image sensor

  图像传感器

• Matte focusing screen

  哑光对焦屏

• Condenser Lens

  聚光镜

• Pentaprism

  五棱镜

• Eyepiece/Viewfinder

  目镜/取景器

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。
