摘要

Models of the human visual system are particularly interesting to quantify the quality of the display systems and to predict if visual information will be perceptible or not. One of these models is the Contrast Sensitivity Function (CSF) which characterizes the sensitivity of the visual system to the spatial and temporal frequencies. The achromatic CSF can be measured, relatively, by a method of pairing which consists in matching the contrast of a test grid with that of a reference grid. To determine the reproducible grids on a screen, it is practical to use a frequency/observation distance diagram. The tests of this study are carried out under the conditions of medical diagnosis for radiographies with sinusoidal stimuli. The obtained results were approximated by a model in order to facilitate their integration in other models.
