ABSTRACT:
A modulating device based on the principal of frustrated total internal reflection that functions over a wide range of angles and wave lengths. The modulator is comprised of two refractive elements that initially are in contact. The edges of the elements are forced apart by a piezo electric transducer and the elasticity of the second refracting element lifts the center of that element away from the first refracting element. The amount of reflection at the interface of the two refractive elements is a function of their spacing. This reflection is reduced to zero by the addition of a thin plastic layer on the surface of one of the refracting elements which allows total contact across the entire surface of the two refractive elements.
