Abstract

An apparatus, system, and method for a front-projection screen having a subsurface diffusion target are disclosed herein.

Claims

1. A method comprising:

forming a refractive element on a first surface of a first layer; and

coupling a reflective diffusion target to a location on a second surface of the first layer to receive radiation incident upon the refractive element within a first range of angles.

2. The method of claim 1, further comprising:

coupling a third surface of an absorption layer to the second surface, the absorption layer adapted to receive radiation incident upon the refractive element outside of the first range of angles.

3. The method of claim 2, wherein the coupling of the reflective diffusion target further comprises:

printing the diffusion target on either the second surface or the third surface.

4. The method of claim 3, wherein at least a portion of the first layer comprises a photo-plastic material having absorptive properties and the method further comprises:

irradiating the refractive element with radiation adapted to affect the irradiated photo-plastic material in a manner to provide a transmissive aperture through the photo-plastic material having absorptive properties.

5. The method of claim 4, wherein the irradiating of the refractive element is done within a third range of angles that approximate angles of anticipated use, the third range of angles being the substantial equivalent of the first range of angles.
