RT Journal Article T1 Corrections to Raman-Nath Diffraction by Volume Holograms A1 Juncos del Egido, Purificación A1 Calvo Padilla, María Luisa AB In this work we present a general formulation of the corrections to the Raman-Nath approximation for the diffracted field by a volume hologram, based on integral equations. An approximate analytic expression is given for the first correction. Numerical evaluations of this correction are also presented. PB Taylor and Francis Ltd.
