Abstract
We performed an investigation on Bragg reflection gratings recorded in blue-sensitive holographic polymer dispersed liquid crystals. The use of a position-sensitive detector allows selective measurements of the reflected light, never before reported in these materials, to our knowledge. We can show that by using this experimental technique it is possible to detect the formation of multiple gratings, even when the transmission spectrum does not show multiple peaks. The results are discussed in the frame of existing coupled-wave theory for anisotropic materials, allowing us to obtain the optical characterization of the gratings.
