Abstract: A split exit pupil heads-up display (HUD) system and method. The HUD system architecture makes use of a split exit pupil design method that enables a modular HUD system and allows the HUD system viewing eye-box size to be tailored while reducing the overall volumetric aspects. A single HUD module utilizes a micro-pixel imager to generate a HUD virtual image with a given viewing eye-box size. When integrated together into a single HUD system, a multiplicity of such HUD modules displaying the same image enables an integrated HUD system to have an eye-box size that equals the same multiple of the eye-box size of a single HUD module. The brightness of the integrated HUD system is maintained while the eye-box size becomes multiple size of the eye-box of a single module. The integrated HUD system can be comprised of multiplicity of single HUD modules to scale the eye-box size to match the intended application while maintaining system brightness.
