Claim 10:
11. A computer-implemented method for computing an optical density of visual pigments, comprising:
receiving a reflectance spectrum indicative of light reflected from a retina of a dark-adapted eye;
receiving a reflectance spectrum indicative of light reflected from a retina of a light-bleached eye;
determining a scattering spectrum; and
computing the optical density of visual pigments in dependence thereon,
wherein determining the scattering spectrum comprises:
receiving data from a detector indicative of a reflected wave of radiation reflected from the retina, wherein the reflected wave of radiation is formed by an incident wave of masked radiation directed towards a retina of the eye, such that at least one region masked from the incident wave is present on the retina;
determining a first back scattering spectrum indicative of light scattered from an optical media of the eye in dependence on a portion of the reflected wave of radiation corresponding to the at least one masked region;
determining a second back scattering spectrum indicative of light scattered from a neural retina of the eye in dependence on retinal structure information representative of neural retinal structure; and
determining the scattering spectrum of the eye in dependence on the first back scattering spectrum and the second back scattering spectrum.
