Diffractive optical elements(DOEs), which are basic elements of the augmented reality(AR) technology, should be required optical Fourier surfaces(OFSs) which consist of sinusoidal gratings that can be minimized optical loss rather than binary gratings. This is possible using azobenzene containing polymer(i.e. azo-polymer). Azo-polymer can occur mass-migration along the polarization of light, which is proportional to the intensity. Based on these properties of azo-polymer, perfect OFSs can be fabricated through holographic inscription without additional process. In addition, this method has a great advantage in the production of DOEs because of its high throughput compared to other lithographic method. In this talk, I’ll briefly introduce optical properties of azo-polymer and talk about how to fabricate perfect OFSs. Furthermore, through analyzing the Fourier spectrum and fabricating wave-guide type DOEs, we intend to suggest that azo-polymer can be used for actual AR display. |
