Abstract
In one example, an eyepiece has a one-piece shape that is solid and rotationally asymmetric. The eyepiece includes first, second and third surfaces at least partially defining the one-piece shape. The first surface is configured to receive a spatially modulated light beam. The second surface is configured to internally reflect the spatially modulated light beam toward the third surface. The third surface is configured to reflect the spatially modulated light beam toward and through the second surface. Transmission of the spatially modulated light beam through the second surface concentrates the spatially modulated light beam.
