Wavelength Discrimination for Point Sources

Not Accessible

Your library or personal account may give you access

Abstract

Wavelength discrimination curves have been measured for two normal trichromats for three field sizes and various intensities. In order to obtain high-intensity levels in the blue region, a high-pressure xenon arc was used as a source. Results for the 1° field agree essentially with those of previous workers. The higher blue intensities have led to the establishment of a definite minimum at 420 mμ. Results for the smaller field sizes differ considerably from previous data. The chief reason for this seems to he in the viewing technique used. While previous authors employed strict fixation, this paper reports data obtained with a scanning technique. The effect of different methods of plotting is briefly discussed.
