| Resumo: | Optical fields that presents periodicity through the axis of propagation are called “self-imaging” fields. Such fields give rise to the well-known Talbot and Lau effects, which have had a lot of attention these last years due to the applications associated to them. Some authors define a partially coherent self-imaging field as that which its cross-spectral density function is the same for two planes separated by a distance d. We have found the coherent mode-representation of self-imaging fields within the frame of the coherence spectral theory formulated by Wolf, we have proven that when we consider complete coherence of the field, we obtain the general expression for self-imaging fields and in the case when we have the superposition of an infinite numbers of coherent modes then we obtain the expression for the Lau effect. |
