PURPOSE: A diffuser having a thin profile which retains wide optical scattering power when embedded in other materials and have low optical back-scatter and therefore higher optical efficiencies than conventional diffusers, are provided. CONSTITUTION: An optical diffusing structures can be fabricated from photopolymerizable material by directing light through a transparent or translucent substrate and then through the photopolymerizable material for a period of time sufficient to photopolymerize only a portion of the material. The resultant structure can be utilized as a diffuser(432), a viewing screen, and in other applications, and can be combined with other light-directing structures such as arrays of tapered optical wave guides. |
