Paper Abstract

Many experiments in physiological optics, optical design, digital image processing, robotics must take into account the behaviour and the contribution of the optical system of the eye (cornea, crystallin lens) as part of the whole system. But, if we need some informations about visual functions, we must take the role of the retina (representing the detector of the eye system) into account. The mosaic formed by retinal photoreceptors initiates the visual process by converting the continuous image transmitted by ocular optics to a discrete array of signals. Thus, the photoreceptor mosaic provides all spatial informations to higher stages of visual process. The photoreceptors have two functions : to conduct light to the pigments (optical function) and then to convert light energy into a neural response (photochemical function). Therefore we have been developping a computer model of the human eye including the spatial structure of the photoreceptors in the retina in order to study their role in the visual system. Our model predict the light illuminance of a spatially modulated visual stimuli on the retina and the absorbed flux in the photoreceptors.
