Abstract
A reflective/diffractive light valve system collects light from multiple dimensions around a single light source. From these multiple collection dimensions, the light is directed to impinge on the valve from multiple directions. When the valve is configured to be reflective, the light returns to the source. On the other hand, when the valve is configured to be diffractive, light from a first and third order diffraction are transmitted from the valve for each of the collection dimensions which greatly enhances the efficiency of the system.
