Abstract

The normal model of light propagation through a turbulent atmosphere is used to investigate the telescope–atmosphere transfer function in stellar speckle interferometry. The effect of the finite bandwidth of a spectral filter on the transfer function is considered. The permissible focusing errors for successful processing in stellar speckle interferometry are obtained based on the normal model. Some observational results are presented and compared with theory. The normal model leads to an analytically simple solution and properly describes light scattering from turbulent atmosphere. The results for the normal model are compared with those for the log-normal model.
