Abstract | A chart and method for measuring and quantifying generalized visual sensitivity in terms of contrast sensitivity and spatial frequency response. The chart contains a multiplicity of grating patches whose contrast, in terms of luminance, varies sinusoidally for differing spatial frequencies. The threshold levels of contrast and spatial frequency at which the presence of gratings can be detected accurately defines generalized visual sensitivity. |
