Real images can be projected onto screens, because the light rays from an object are actually traveling there.

实际图像可以落在屏幕上,因为身体的光线实际上正在向它传播。

实像

上:凸透镜所成的实像。下:凹面镜所成的实像。图中黑色箭头O为物体,灰色箭头I为实像,f为镜的焦点,蓝色箭头是光路。
图为凸透镜成的实像。实像是倒立的,像上的点与物体上的点一一对应。
Objet réel et Image réelle recueillie sur un écran.
Gadget optique formé par deux miroirs paraboliques opposés permettant d'observer une image réelle.

实像英语:real image)是物体发出的光线经光学系统折射或反射后,重新会聚而形成的与原物相似而倒立的像。简言之,『实像就像真实物体,可以直接看到。』 实像就有如在成像处的真实物体,其实,受到周边物体比对的影响,往往人脑的视觉感官就可以判断确知此实像的位置,直到人类尝试碰触此实像时,才会因为人脑的触觉感官而发现其实此实像所在处其实并无实物,碰触不到。 实像能用光屏承接,在像的位置放置光屏就能接收到清晰的像,摄影或放映电影都需利用成实像的原理。相对原物体而言,实像总是倒立的,上下左右都会颠倒。

Real image 实像

 Top: The formation of a real image using a convex lens. Bottom: The formation of a real image using a concave mirror. In both diagrams, f  is the focal point, O  is the object and I  is the image. Solid blue lines indicate light rays. It can be seen that the image  is formed by actual light rays and thus can form a visible image on a screen placed at the position of the image.
Producing a real image. Each region of the detector or retina indicates the light produced by a corresponding region of the object.
Objet réel et Image réelle recueillie sur un écran.
Gadget optique formé par deux miroirs paraboliques opposés permettant d'observer une image réelle.

In optics, a real image is an image which is located in the plane of convergence for the light rays that originate from a given object. If a screen is placed in the plane of a real image the image will generally become visible on the screen. Examples of real images include the image seen on a cinema screen (the source being the projector), the image produced on a detector in the rear of a camera, and the image produced on an eyeball retina (the camera and eye focus light through an internal convex lens). In ray diagrams (such as the images on the right), real rays of light are always represented by full, solid lines; perceived or extrapolated rays of light are represented by dashed lines. A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to converge.
