Hi,
a rectangle drawn via a scanhead is typically distorted in a funny way (two sides bent to the inner, two to the outer side). This can be even stronger when some optics are used - and of course all geometries are affected, not only rectangles (but there one can see this easily).
My question: is there a formula available which can be used to correct these distortions? Until now I only know the possibility to have static (and not so accurate) correction tables...
Thanks!
