Abstract
There is provided a method of operating a wearable heads-up display (WHUD), which method includes generating first and second lights having respectively first and second wavelengths within about 50 nm of one another. The method also includes directing the first and second lights onto an incoupler of a display optic of the WHUD along first and second ranges of input angles respectively. The first and second ranges of input angles correspond to positions of pixels of first and second portions of an image to be displayed by the WHUD. The incoupler has first and second angular bandwidths corresponding to the first and second wavelengths respectively. A combination of the first and second ranges of input angles is larger than each of the first and second angular bandwidths. Moreover, the method includes directing the first and second lights into a field of view of a user to form the image.
