Abstract: 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.

Abstract: A light integrator produces diffuse illumination from a beam of light wherein image artifacts due to debris within the integrator are suppressed. The light integrator includes an integrator block having an elongated cylindrical light integrating cavity enclosed by end walls and a longitudinal cylindrical chamber wall having a diffusely reflecting interior surface The chamber wall includes a longitudinally extending output slit for emitting light from the cavity. A dust-free zone exists within the cavity in the shape of a sector of a circle within which contaminants cannot come to rest without producing visible artifacts, wherein the origin of the sector is located at or nearby a plane of the original. An elongated light pipe extends into the cavity through one of the end walls, where the light pipe has an input port at one end thereof for introducing the beam of light and a treatment along its length for emitting light entering its port into the cavity. At least one of the end walls forms a support for the elongated light pipe so that the light pipe extends along a length of the integrating cavity outside of the dust-free zone and in relation to the chamber wall thereof to direct light emitted therefrom toward the diffusely reflecting interior surface.
