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