The optical discontinuities located at domain walls in low-symmetry ferroelastics are responsible for the light-deflection phenomenon and for subsequent impairments of the intensity, the phase coherence, and the polarization of the direct beam transmitted through the domain structure. Here, intensity losses are studied. Degradations of the coherence and the polarization are addressed in a companion paper. The deflected intensities are calculated as a function of the domain-wall density and of the average deformation of the polydomain sample. At first, a random phase hypothesis is assumed, then the calculation is refined by a two-wave interference model. Dichroic effects in deflection are predicted.
