The effect of spatial dephasing between the absorption and phase grating which was previously presented in transmission gratings is now developed for reflection ones. The effect is presented analytically and evaluated numerically for several cases. The analysis is motivated by the photorefractive effect in electro-optic crystals.journal articlehttp://dx.doi.org/10.1007/BF02030991http://link.springer.com/metadata only access535Electrical and Electronic EngineeringOpticsÓptica (Física)2209.19 Óptica Física
