Abstract
Contrast threshold was measured psychophysically for a sinusoidal grating presented periodically with a variable temporal frequency for various parameters of patterns. Special attention was paid to the range of high spatial frequencies as defining the resolving power of the eye. Within this range, the contrast threshold were found to be almost independent of many parameters of patterns. It was also found that the sum of certain spatial and temporal resolution indices was proportional to the logarithm of the contrast; this sum was also a logarithmic function of the average luminance in the mesopic range of luminances. © 1971.
