Thanks, yep they have some attribute that I was looking for but they are way to expensive (yes I am an engineer).
Can I do this on other material ? like polarize and control light diffusion. Because I was thinking on some sort of smart light diffuser curtain.Thanks and regards.
How can I control the refractive index on a material, I mean on what depends the refractive index?
Because I am trying to create like a controlable light diffuser mechanism.
Thanks and regards.
