Abstract:
The modelling of the human eye involves both detailed knowledge of the structure as well as its optical properties. POV-Ray was used in this project to realistically model the anatomical features of the human eye. A linear matrix method was introduced as a novel method of calculating point spread functions of rotationally symmetric and astigmatic eyes, from which the visualisation of images formed on the retina of an eye can be achieved. This method was validated by comparing the point spread functions, modulation transfer functions and the volumes under the modulation transfer functions of eyes with different conditions. The convolution of a given image with the point spread function of an eye allowed the simulation of sight through the eye to see the image. The linear matrix method therefore proves a feasible method for the simulation of human vision. More possible research areas to improve on this linear matrix method include the simulation of retinal and brain processing, and the effects of diffraction.
