“…Therefore imporving the FOM helps to transform the viewing zone into a preferred shape. The ray-tracing model is the usual method to simulate the intensity profile of a lenticular lens array based auto-stereoscopic display [26], [27]. One of the efficient ways to simulate the intensity profile is proposed in [26].…”

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.

Three-dimensional analysis of the optical functionalities of an autostereoscopic display with an array of slanted lenticular lenses was performed. The specification parameters of the lenticular lens for clear separation of the images were first determined using the geometrical optics, and the transmission characteristics of the light ray travelling through a single lenticular were then calculated by finite ray tracing. The properties of light transmission over the entire display panel were then determined by expanding the results obtained for the single lenticular to the entire lenticular lens array. Consequently, each view was confirmed to be located at an interocular distance of 65 mm away from each other. Approximately 5% noise was observed between the views, and the shape of the viewing zone at the optimal viewing distance was tilted towards the direction of the slanted lenticular. Overall, numerical analysis enables a realistic evaluation of the optical functionalities, such as the shape of the viewing zone, of lenticular based autostereoscopic displays.
