摘要： A mechanical grating device for enhancing the reflective properties is presented. A mechanical grating has a plurality of parallel ribbon elements which are suspended above a channel. An incident light beam is modulated by the actuation of selected ribbon elements. The actuation of the ribbon elements, which changes the height of the ribbon elements relative to the substrate, is a result of an applied voltage that produces an electrostatic force. On the top surface of the ribbon elements is a coating of reflective metal upon which is an optical coating is provided. The optical coating is a stack of at least two different materials with different refractive indices. The thickness and the composition of the sequential layers in the stack are chosen to produce certain desired reflective properties. Embodiments are presented for reducing the mechanical effects of the dielectric optical coating.

摘要： A method for operating an electro-mechanical grating device comprises the steps of: providing a beam of light; applying a first electrostatic actuation force for a certain amount of time thereby generating a first pattern in each group wherein the pattern comprises N different levels thereby diffracting the incident light beam into a first direction; and applying a second electrostatic actuation force for a certain amount of time thereby generating a second pattern in each group wherein the second pattern comprises N different levels thereby diffracting the incident light beam into a second direction different from the first direction. The electro-mechanical grating device has a plurality of spaced apart deformable ribbon elements disposed parallel to each other in the unactuated state and spanning a channel. The deformable ribbon elements are organized in groups of N elements wherein N is greater than 2. A plurality of standoffs are provided, wherein according to the longitudinal direction of the electro-mechanical grating device at least N-2 standoffs are associated with each group.
