Mapping law

In optics, the image law is understood to be the mathematical or geometric description of the relationship between the object and the image.

These are based on optical systems such as B. Lenses and mirrors applicable. For a further description, see the optical illustration .

The mapping law reads:

${\displaystyle V={\frac {B}{G}}={\frac {b}{g}}}$ ,

where V is the image scale , G is the object size , B is the image size , g is the object distance and b is the image distance . The law of mapping follows directly from the ray theorem .
