Formation and Sampling of the Retinal Image

摘要: Publisher Summary Vision begins with the formation of an optical image external world upon retinal mosaic light-sensitive photoreceptors. Because is very first step in visual process, imperfections eye's apparatus have potential for affecting every aspect perception, from color to motion, space, and form. Even if focusing components system were perfect, would still be degraded by diffraction light as it passes through pupil. Another limiting factor vision scattering traverses ocular media retina before being absorbed pigment molecules inside Thus, study perception must logically begin imaging properties eye uncover those factors that constrain quality vision. This chapter aims succinctly review current understanding sampling human limitations imposed these initial stages process. When taken together, this neuro-optical model provides a conceptual framework interpreting empirical studies limits impact two daily life.
