Abstract:

We show in this paper that the generalized optical transfer function (OTF) of the turbulent atmosphere and receiving system, corresponding to the laws of linear filtration, can be constructed for the case of diffuse object illumination with incoherent optical radiation along a correlated path. At diffuse object illumination with a coherent radiation along a correlated path, one fails to construct an OTF meeting the principles of linear filtration. It has been established that when transceiving apertures of a coherent source and a telescope are matched, the account for the correlation between the wave illuminating the object and that reflected from it improves the quality of short-exposure image.
