A system and method for recording a reflection Bragg Grating in a photosensitive target. A photosensitive target is located between transmissive members on three sides. Beams incident on one of the transmissive members pass through the other two members before creating an interference within the photosensitive target. Either two transmissive members are used and the second member limits angular mobility of the first, or three members are used and the third member limits angular mobility of the other two. The target is coupled to the transmissive members through a transmissive liquid that has a refractive index similar to the refractive index of the target. Accordingly, angular deviations in the location of the target from the intended location or in the shape of the target only negligibly impact the interference pattern of the beams in the photosensitive target.
