Abstract
A figure-of-merit (FOM) of an auto-stereoscopic display
system is introduced and adopted to characterize the system performance. This
FOM takes into account of the ratio of the signal to the noise arising from
the crosstalk from the adjacent channels as well as the brightness uniformity
of viewing areas; hence, it is directly related to the glasses-free 3D viewing
comfort. With a steadily improving FOM as a target, the genetic algorithm
is applied to optimize the optical system, giving rise to substantially improved
characteristics of an auto-stereoscopic display system. The numerical simulation
is verified with an experiment of a multi-view auto-stereoscopic display unit.
It is shown that the system can provide a high fidelity of the display effect
with the crosstalk ratio being reduced from around 5% to nearly 1%, which
is a very low value obtainable for an auto-stereoscopic system.
