ABSTRACT:
This modulator mirror comprises at least two partially transparent reflector stacks bonded to two separate substrates held apart by spacers to create a parallel gap between the partially transparent reflector stacks wherein the gap has a reference spacing of an even number of quarter wavelengths of the light energy contained within the beam to be modulated. The modulation is accomplished by causing a physical displacement between the two substrates such that the gap spacing varies between the reference pass position of the even number of quarter wavelengths and a second reference no pass position of about .+-. one quarter wavelength. The physical motion may be accomplished by electrostatic, piezo-electric, magnetic or other means.
