Conclusions
For holography using a convergent subject beam arrangement, the effect associated with increased extrafocal information density is most pronounced when the parameter 2ac/λF is small. This relationship between the object parameters (a and c) and the characteristics of the holographic system (λ, F) is encountered most frequently in problems of microfilming (a≪c) and radar imaging (a∼c,a 2/λF is small). It is only in the case 2acλF≥99 with an accuracy of not worse than 1%, that we can assert that the sizes of the “minimal” Fourier holograms will coincide.
