[ATM] Measuring scattered light off optical surfaces

[Tom Krajci]

What amateur techniques are used to quantitatively measure scattered light
off optical surfaces?  I know of various go/no-go tests for evaluating
quality of polish, but what about quantifying the amount of scatter of a
polished surface, or an aluminized surface?

Thanks in advance.
