Abstract
The invention concerns a method for photographic recording a spatial distribution of linear and/or non-linear optical properties in a polymer material which consists in irradiating the material to modify the orientation of its molecules. The irradiation direction is perpendicular or oblique relative to the propagation direction(s) of the scanning beams.
