We suggested a mathematical model describing optical phenomena at the surface of a lenticular array for
autostereoscopic displays in 2-view system and simulated the angular distribution of light using Monte Carlo methods
under actual design conditions. By comparing the results of our simulation model with those of the conventional
simulation tool, we showed good agreement between our model and conventional tool in calculating the angular
distribution of light. We also achieved simulation time of 60% faster than the conventional design tool. From the results, we think our optical model is very useful for designing optical parameters of autostereoscopic displays.
In this study, we suggest a new concept of 3D crosstalk for auto-stereoscopic displays and obtain 3D crosstalk values of
several multi-view systems based on the suggested definition. First, we measure the angular dependencies of the
luminance for auto-stereoscopic displays under various test patterns corresponding to each view of a multi-view system
and then calculate the 3D crosstalk based on our new definition with respect to the measured luminance profiles. Our
new approach gives just a single 3D crosstalk value for single device without any ambiguity and shows similar order of
values to the conventional stereoscopic displays. These results are compared with the conventional 3D crosstalk values
of selected auto-stereoscopic displays such as 4-view and 9-view systems. From the result, we believe that this new
approach is very useful for controlling 3D crosstalk values of the 3D displays manufacturing and benchmarking of the
3D performances among the various auto-stereoscopic displays.
