BEAM EXPANDER AND METHOD OF OPERATING THE SAME

A beam expander includes first and second optical elements spaced apart from each other, and a light diffuser having an angular aperture that diffuses incident light through the angular aperture, wherein the first optical element in-couples the diffused light such that light exiting the first optica...

Beschreibung
Zusammenfassung:	A beam expander includes first and second optical elements spaced apart from each other, and a light diffuser having an angular aperture that diffuses incident light through the angular aperture, wherein the first optical element in-couples the diffused light such that light exiting the first optical element has a first cross-sectional shape and light having a second cross-sectional shape different from the first cross-sectional shape is incident on the second optical element, and the second optical element out-couples light incident from the first optical element.
