Disclosed herein is a variable grating diffractive light modulator, which actuates lower reflecting plates of a lower reflecting array by a piezoelectric actuating method, and includes an upper reflecting array that is spaced apart from the lower reflecting array and attached to a lower surface of a substrate that is made of a light transmissive material and covers the lower reflecting array, so that the light modulator reflects incident light transmitted through the substrate and thereby produces diffractive light.

Variable grating diffractive light modulator

Disclosed herein are an electrostatic-type variable diffractive light modulator, which includes lower micromirrors that are provided on a glass substrate to be spaced apart from each other, and actuates upper micromirrors that are spaced apart from the substrate by an electrostatic actuating method, thus allowing the upper and lower micromirrors to diffract incident light entering a lower portion of the substrate, and a method of manufacturing the electrostatic-type variable diffractive light modulator.
