10.1: Distinguished Paper: Evaluation of Moving-Line Contrast Degradation without Motion

This paper introduces a method for evaluation of the contrast of a moving lattice (grille) pattern without imaging data acquisition and image analysis. We characterize the dynamic performance of the display under test in terms of periodic responses followed by evaluation of the dynamic contrast from the temporal variation of luminance. It thus becomes possible to simulate moving grille patterns with any pitch, arbitrary gray-levels and speed of translation by measuring the corresponding temporal luminance variations at a fixed location. This approach is attractive due to reduced instrumental efforts and the transparent evaluation based on suitable spatial contrast sensitivities.
