1. An image guide device, comprising:
a digital micromirror device (DMD) with an illumination source optically couple thereto;
wherein a plurality of wavelengths from the illumination source each have a total field of view (FOV) and the DMD divides the total FOV into sub-FOVs;
an image guide having an input grating and output grating, the input grating optically coupled to the DMD such that the image guide receives the plurality of wavelengths with sub-FOVs from the DMD at the input grating;
a holographic waveguide optically coupled to the output grating of the image guide such that the holographic waveguide receives the plurality of wavelengths with sub-FOVs and multiplexes the plurality of wavelengths to the total FOV.
