Pixel response spectral responsivity (SR) as a function of wavelength
SR = pixelSR(pixel)
The SR measure has units of volts/watt. The measurement is basically the
same as spectral quantum efficiency, but measured with respect to input
energy of the light rather than quanta.
SR(lambda) = (lambda*q)/(h*c) * QE(lambda);
where q is the charge/electron, h is Planck's constant, c is the speed of
light, lambda is the wavelength of the in put, and QE is the spectral
quantum efficiency.
