Real picture

Real image is a term from geometric optics . It describes images from which really (in “reality”, therefore real ) rays of light emanate. At the location of the real image there can be a screen from which rays of light emanate that have met there ( screen image). If the screen is missing, the light rays diverge again and can be perceived directly when they hit the eye (spatial image).

When an object is mapped from the object space, it can be transferred into the image space as a real image. A real intermediate image can in turn be transferred as an object into a further image space.

The opposite is the virtual image , which can never be displayed on a screen, but can only be made visible, for example, with an eye or a camera .


Important examples of real images are:
