In sensor systems, where the output is easily quantified, the responsivity can be extended to be wavelength dependent, incorporating the spectral sensitivity.
22.
The normal human eye contains three different types of cone, with different ranges of spectral sensitivity; hence the cones enable us to distinguish different colors.
23.
Because of frequent recombination during meiosis, these gene pairs can get easily rearranged, creating versions of the genes that do not have distinct spectral sensitivities.
24.
Variations in OPN1MW, which codes the opsin expressed in M cones, appear to be rare, and the observed variants have no effect on spectral sensitivity.
25.
To this end, both the observer s spectral sensitivity and relative number of cone types have proven to not play any significant role in perceiving different hues.
26.
They also reduce the overlap in spectral sensitivity between different types of cone ( e . g . short wavelength sensitive, medium wavelength sensitive etc . ).
27.
The method is to apply a gain to each of the human cone cell spectral sensitivity responses so as to keep the adapted appearance of the reference white constant.
28.
The "'luminosity function "'or "'luminous efficiency function "'describes the average spectral sensitivity of human visual perception of brightness.
29.
In 1873, Hermann Wilhelm Vogel discovered that the spectral sensitivity could be extended to green and yellow light by adding very small quantities of certain dyes to the emulsion.
30.
Some double cones have members with identical visual pigments ( twin cones ), while others have members with different cone types ( members have a different spectral sensitivity ).
