BULK DIFFUSER FOR A PROJECTION TELEVISION SCREEN

A bulk diffuser for rear projection television screens which exhibits a Gaussian intensity profile is described. By appropriately selecting the indices of refraction of the substrate and the loading density and the range of diameters of the spheres therein, the intensity half-angle is made equal to...

Zusammenfassung:	A bulk diffuser for rear projection television screens which exhibits a Gaussian intensity profile is described. By appropriately selecting the indices of refraction of the substrate and the loading density and the range of diameters of the spheres therein, the intensity half-angle is made equal to the energy half-angle, whereby the intensity profile of the bulk diffuser is Gaussian.
