Abstract:
A reflective light processing element capable of modifying at least one characteristic of an optical beam, comprising: a plurality of wide reflective surfaces, the wide reflective surfaces being substantially coplanar; a plurality of narrow reflective surfaces, the narrow reflective surfaces being substantially coplanar, the narrow reflective surfaces facing substantially a same direction as the wide reflective surfaces, the narrow reflective surfaces alternatingly arranged with the wide reflective surfaces, the narrow reflective surfaces and the wide reflective surfaces defining a plurality of gaps between and normal to the narrow reflective surfaces and the wide reflective surfaces; and a plurality of compensating reflective surfaces, the compensating reflective surfaces being substantially coplanar, the compensating reflective surfaces facing substantially the same direction as the narrow reflective surfaces and the wide reflective surfaces, the compensating reflective surfaces being positioned in each gap beneath the narrow reflective surfaces and the wide reflective surfaces, each compensating reflecting surface being at least as wide as each gap; wherein the wide reflective surfaces are capable of a displacement in a direction normal to the narrow reflective surfaces and compensating reflecting surfaces, the displacement of the wide reflective surfaces capable of modifying at least one characteristic of the incident optical beam.
