Hello Physics Forums goers:
Ok, I have a project that deals with image analysis. The idea is to make the process very easy upon myself and make the background on which I will place objects as dark as possible.
1st idea I have is that of a surface that will polarize light when light reflects from it. I googled for such a surface and I couldn't find any.
2nd idea is to have a surface that deflects or reflects away a polarized light.
3rd idea is to have a non-reflective surface that absorbs most (if not all) light that falls upon it. Again, I couldn't find any such material for sell.
ANYONE KNOW WHERE I CAN BUY ANY ONE OF THESE SURFACES?
Thanks in advance.
p.s. 1- the material can not be velvet or anything that can not be wiped with a piece of damp cloth.
2- the material should withstand a medium vibration (a bit above cellphone vibration) for 10 minutes at a time.
