| Abstract: | A holographic optical element (HOE) simultaneously accompanied with light guiding and beam shaping function is implemented with edge-lit holograms in this study. This holographic optical element is generated in a polymer-dispersed- liquid-crystal (PDLC) film with 20μm thickness. In the holographic reconstruction process of the HOE, the wavefronts emitted from the light source will propagate to the HOE and a quasi collimation diffraction beam can be obtained from this device. We demonstrate two applications of edge-lit HOE in this study. One demonstration is a head-mounted display (HMD) system, and the other is an illumination device for display holograms. |
