Abstract

Waveguide-type optical combiners with holographic optical element couplers are advantageous in augmented reality field, especially for near-to-eye displays, with their structural features such as optical see-through capability, compact form factor, and high diffraction efficiency. The structural features of the waveguide-type optical combiner can also be utilized when it is adopted for floating displays. In this paper, waveguide-type floating display using holographic optical elements with convergent power is proposed as a new method of adopting waveguide-type optical combiner structure. The waveguide configuration enables highly compact form factor. Changing the depth of the floating images can be conveniently applied by using the output holographic optical element coupler recorded with different convex lens. Experimental results demonstrate that waveguide-type floating display with convergent power is feasible as a new method of applying waveguide optical combiner.
