Abstract
A theoretical model for quantifying the effects of the sampling aliasing on the viewing resolution of the reconstructed integral image is proposed. Specifically, the “squeezed” modulation transfer function (MTF) concept is introduced to characterize the quality degradation of an integral image due to the sampling effect. Then, for the display part of an integral imaging system, an analytical model for the squeezed MTF is derived by defining a spurious response factor related to the sampling aliasing of the display microlens array. Finally, we analyze the quantitative relationships of the viewing resolution of an integral image with the sampling step size determined by the pitch of a microlens array, and the distance from the displayed microlens array to the display device based on the simulation results.
