ABSTRACT:
Disclosed are an apparatus and method for separately detecting and measuring specularly reflected light and diffusely reflected light following illumination of an eye by light. The apparatus and method of the present invention facilitates substantial separation of the diffusely reflected light from light specularly reflected from the eye after passing through one or more elements of the eye, for example, the cornea, lens, retinal vasculature, the nerve fibre layer and/or the photoreceptors. The collection of these separate streams of independent optical signals to appropriate detection systems provides specificity and accuracy in determination of optical properties of one or more elements of the eye.
