Abstract

Disclosed are systems and methods for providing illumination in a head mounted display. In one embodiment a method includes emitting light from a plurality of sources at a plurality of wavelengths and transmitting the light from the plurality of sources to a first device. The method further includes combining the light, utilizing the first device, from the plurality of sources into a combined light signal and creating telecentricity in the combined light signal. The method also includes receiving a telecentric light signal on a display surface. In one embodiment the system includes a light source, a hybrid reflective structure configured as a truncated pyramid and further configured to transmit light emitted by the light source and an optics device configured to create telecentricity in light that was transmitted through the hybrid reflective structure to a display surface.
