How to control the refractive index?

  1. Mar 18, 2015 #1
    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.

    Welcome to the PF.

    Are you familiar with Liquid Crystals? Maybe do some reading on them to see if they will give you what you want.

    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.
