Abstract
Examples are disclosed that relate to holographic near-eye display systems. One example provides a near-eye display device, comprising a diverging light source, an image producing dynamic digital hologram panel configured to receive light from the diverging light source and form an image. The near-eye display device also includes and a combiner comprising a holographic optical element positioned to receive light from the dynamic digital hologram panel and to redirect the light toward an eyebox, the holographic optical element being positioned between the eyebox and a view of an external environment to combine a view of the image formed by the dynamic digital hologram panel and the view of the external environment.
