Modeling spectral sensitivity at low light levels based on mesopic visual performance
The spectral sensitivity of the eye at low light levels, ie, mesopic conditions, is determined by the rod and cone photoreceptors of the retina operating together in varying degree as adaptation luminance shifts between the scotopic and photopic. Thus mesopic spectral sensitivity is different from photopic, where only cones contribute to vision. There are definite needs for a practical system o...

Characterising mesopic spectral sensitivity from reaction times
The spectral sensitivity of the eye was investigated using reaction times to broadband chromatic stimuli over a range of background luminances. Relative sensitivity was determined from the nonlinear reaction time curve by converting reaction times to a linear measure that was independent of spectral sensitivity. Two models for mesopic spectral sensitivity were compared. The first was a linear c...
متن کاملDriving in Snow: Effect of Headlamp Color at Mesopic and Photopic Light Levels
Many individuals believe that yellow headlights are preferable to white headlights when driving at night during a snowfall. Although evidence exists to support the claim that yellow light can be perceived as less “glaring” or “distracting” than white light of equal luminance, it is not clear whether backscattered light of different colors are differentially effective for driver comfort or for d...
متن کاملThe development of a mesopic spectral sensitivity curve based on visual observation , and the question of spectral additivity in the mesopic luminance region PhD thesis extract
The aim of the research was to establish an appropriate detection contrast metric in the mesopic luminance range which solves the problem of non-additivity by taking the influence of the chromatic channels into account. Based on several experiments at 10° and 20° eccentricity, and further theoretical modeling the CHC2 contrast metric was constructed, which takes the influence of the chromatic c...
