Abstract

Some aspects of the application of the linear systems approach and the method of the Green’s functions to the theory of vision in scattering media are refined. The physical meaning of the influence function and the optical transfer function of scattering media and vision systems are discussed. It is stated that the physical meaning of the concepts of the optical transfer function and the impulse response (point spread function or influence function) of scattering media or an imaging channel in scattering media is uncertain if the reflection (emission) properties of the object plane (surface) are undetermined. The main differences between the characteristics of linear systems for optical imaging and vision systems are emphasized. A criterion is suggested for estimating the size of the peripheral image isoplanarity zones in vision systems.
