Hi MEMS workers,

I want to measure the deformation of some MEMS scale
or a bit larger structures by Photogrammetry. I need
to have a good distribution of grey areas and white
areas in the images. For this, I have to spray some
tiny dot particles. I need a sprayer of that capacity.
Also, an appropriate spray material would be required.
I tried to use some powders like Titanium oxide and
some other commercially available things but they do
not seem to work for that level. Could anyone suggest
me a way out?

Is it possible to sputter something? It should not
make a continuous deposit, what I need is a contrast
between the different points..

Thanks in advance for your help..
