E3S technologies provide multi-users projection systems combining 3 image multiplexing techniques (time, spectral, polarization) according to requests enabling to provide independent channels from 3 equipped projectors.
All options are, however, not equivalent w.r. to crosstalk, luminance and color balance performance. Time multiplexing is theoretically infinite but in practice limited by the shutter switching time, and the power division (per channel), similarly for spectral options, increase in channel number results in color unbalance, polarization being intrinsically limited to 2.
In this frame E3S proposes two commercial options: regular 4 and premium 6 channels (time/spectral) but can engineer more channels on demand usable for CAVE or multi-view and multi-users displays.
