Calculating the depth of field (DOF)

The depth of field (DOF) is the range within which the object can move away from or towards the camera without resulting in a blurred image. The depth of field depends on the adjusted lens aperture, the distance to the test object, the focal length and the pixel size of the camera. the double pixel size is often set taken permissible unsharpness, i.e. one pixel image unsharpness is accepted.

In an existing system, the field of depth can only be varied by means of the aperture of the lens.
