Technical Examples

Narrow-line holographic filters that can include a plurality of lines and that can be structured to provide a large aperture device. Materials that can be used to construct filters include glasses, photorefractive crystals such as lithium niobate and photorefractive thick polymers. The filters are fabricated by assembling a plurality of elements having the same one or more narrow line holographic filter patterns written thereon, in mutual orientation such that each element has a surface defined by a length and a width adjacent a corresponding surface of a neighboring element, and has a surface defined by a thickness and one of a length and a width accessible to impinging illumination. Filters exhibiting a plurality of characteristic narrow lines, and having arbitrarily large apertures can be fabricated. Methods of fabricating and using the filters are described.
