Optical performance of angle-dependent light-control glass

摘要

Angle dependent light control glass (LCG) is a new glass that scatters only incident lights from particular angles and transmits incident lights from all other angles. This unique light control function of LCG is caused by the microstructure in the specific polymer film sandwiched by a pair of glasses. The optical performance and properties described in this paper support that the principle of an angle dependent light control function can be explained mainly by diffraction due to the microstructure like a stack of various transmission volume phase gratings.
