Some comparisons between foveal spectral sensitivity data obtained at high brightness and absolute threshold.

摘要: The spectral sensitivity of the fovea was measured by three methods on same observers. were: absolute threshold with two sizes stimuli, flicker photometry, and heterochromatic brightness matching. data were analyzed reference to (a) reliability departures from a smooth curve, (b) presence scotopic factor within 2° centrally-fixated field, (c) additivity luminances as determined CIE procedure.The results indicate (1) good correspondence major irregularities at 450–60, 490, 580 mμ, (2) definite components in possible effects 45′ data, (3) for irregularity mμ consistently became sharp loss which delineated twin peaks 540 590–600 mμ. showed very large failure over this region spectrum.
