Abstract
A Moiré deflectometer includes at least three non-mechanical, transparent, spatial light modulators for demonstrating two sets of patterns on two parallel planes on two of the modulators thereby creating a Moiré fringe pattern and a method for using the same. More particularly, each of the spatial light modulators may be a liquid crystal display, an electrochromic device, a micromirror array, a microlouvre array, an electro-optic device, or a holographic device.
