Abstract
A head up display can be used in compact environments. The head up display includes a combiner system including at least one light pipe and a waveguide. The at least one light pipe includes a diffraction grating or mirror array for providing light into the waveguide from the light pipe. The light pipe is configured to receive light and provide first light in a first direction for a first field of view and second light in a second direction for a second field of view. The combiner system can be head worn or stand-alone and can provide dual axis pupil expansion.
