Abstract

The improvement of fill factor of holographic micromirror array (HMA) with holographic waveguide-type for threedimensional (3D) augmented-reality (AR) display system. Our proposed 3D AR system was created and briefly explain it; there have two the HOE optical film at in-and out coupler of the waveguide. In-coupler HOE is our fabricated HMA, it has a same role with optical microlens-array. HMA is integrate the displaying elemental image set (EIS) from micro display which EIS was generated by the integral imaging technology. The micro display has a 6 mm by 8mm size, 48single elemental images and micro display was located g distance from holographic waveguide which waveguide thickness was 5mm. EIS was displayed by micro display to holographic waveguide. HMA was stick with holographic waveguide and located in opposite side of waveguide and micro display. Micro display was display forward to holographic waveguide and fabricated HMA, then displayed EIS is reflected and integrated at the in-coupler HMA and integrated 3D image was through the holographic waveguide by HMA recorded angle. 3D images of internal reflect in the holographic waveguide was 1 time. 3D image was also reflected at the out-coupler HOE which role was same as optical mirror and reflect to observer’s eye. At least observer as the reconstructed images and real object out and reflects by out-coupler HOE.
