QUALITY MEASUREMENTS OF 3 D LIGHT-FIELD DISPLAYS Péter

We present methods to measure the spatial, angular and depth resolution of LF displays using off-the-shelf equipment and performing a subjective experiment. The spatial resolution is measured in circles per degree and the challenge is to display and quantify sinusoidal patterns with varying spatial frequencies on displays, which in general do not exhibit regular or pixel-like structure. Being specific for 3D displays, the angular resolution represents the number of unique directions that can be emitted from a point, and measured in circles per degree. The paper presents the experimental setup and discusses the results. The depth resolution shows the minimum distinguishable depth that can be reproduced by the display used, and is estimated by a subjective experiment.
