Polarization sensitive diffuser

With help of liquid crystal polymers (LCP) a polarization sensitive diffuser has been realized. By using convex microstructures made of LCP and an index matching layer, two distinct functions depending on the orientation of the device and the polarization state of the input light are realized. For one polarization the light pass through the device with no changes and for the perpendicular polarization, the light is diffused by the microstructures
