Claim 18:
19. A device for determining a scattering spectrum of an eye, comprising:
a radiation source for directing an incident wave of radiation towards a retina;
a configurable mask for masking at least one area of the retina from the incident wave;
a detector for detecting a reflected wave of radiation from the retina and outputting information indicative thereof;
a processor configured to access the information indicative of the reflected wave and retinal structure information representative of neural retinal structure and to:
determine 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 of the retina;
determine a second back scattering spectrum indicative of light scattered from a neural retina of the eye in dependence on the retinal structure information;
determine the scattering spectrum of the eye in dependence on the first back scattering spectrum and the second back scattering spectrum; and
extrapolate at least one of the first back scattering spectrum and the second back scattering spectrum to different wavelengths of incident radiation using a scattering model.
