Florian, thanks for explanation. I have read this article :
"Firstly, don't think that it is a bug in POV-Ray. It isn't a bug, but a
real problem caused be the lighting model used in the renderer engine that
is quite difficult to surpass. It's not a problem in POV-Ray in particular,
but a problem in raytracing in general. Every raytracer will have this same
problem when using perturbed surface normals (unless there's some fix coded
into it)."
I rendered this object with other engines, for example Yafray :
I think, this is a deficiency for Povray..
Regards,
Hasan
