The first filter is optical and is characterized by an optical point-spread function. The second filter is neural and is characterized by the neural point-spread function, which is shown to be related to the receptive fields of retinal neurons. Sampling renders the int...
متن کاملStudy of Optical Models Regarding the Human Eye
Introduction: Until now, many models have been presented for optical study of the human eye. In recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. Material and Methods: In this article, some of these models are considered. They incl...
