Paper Abstract
The goal of this work was the optimization of brightness and colors performance of the interference filter system for 3D projection. Special emphasis was on avoiding, or at least reducing, the need for color correction, which was one of reasons for low luminous efficiencies in the past.
On the base of datasets for various projectors (DLP, LCoS, LCD) and lamps (UHP and Xenon), the optimization for a
high efficiency stereoscopic interference filter system was carried out. Focus of our study was on three by four (3-4)
filter system. We also examined filter designs with higher numbers of transmission bands up to seven per filter. The
results show that the 3-4 band filters design exhibits the highest efficiency of all inherently color balanced filter systems
because of a minimum number of gaps between adjacent transmission bands. Results also revealed that Xenon lamp
based systems and UHP lamp based systems have different optimum filters. However, differences are such small that it
becomes possible to cover both systems by a unitary type of 3D glasses lenses.
