Abstract:
1. An optical component comprising: a rigid light guide adapted to conduct light under conditions of total internal reflection; a deformable layer adapted to conduct light under conditions of total internal reflection, the deformable layer having an upper surface disposed on a first surface of the light guide; and an active layer disposed in a spaced-apart relationship to the deformable layer, the active layer configured to physically move between an inactive state position and an active state position, wherein during the inactive state position the active layer is positioned in a spaced-apart relationship to the deformable layer, and wherein during the active state position the active layer is selectively repositioned so as to cause a deformation in a lower surface of the deformable layer such that the light within the deformable layer is reflected off the deformation and ejected from some portion of a second surface of the light guide, at least a portion of the active layer coated with a plurality of small asperities.
