| [* black] Now things get a bit destructive, but it's worth it to get a peek at the optics. | |
| [* red] At the far right of the first image, we have a tiny ring of six LEDs—red, green and blue, times two for two focus planes. Let there be light! | |
| [* orange] Next to that, we have the LCOS microdisplay. | |
| [* yellow] The next item over is just a black chunk of the housing plastic—but next to that, we have the polarizing beam splitter mounted on top of the collimating lens for the LED light. | |
| [* green] Next-to-last is the "injection optics" unit for focusing the image into the waveguide. | |
| [* light_blue] And at the far left, you can see the (slightly broken) waveguide—and if you enlarge it, you can even see the six embedded entrance diffraction gratings, one per waveguide layer. | |
| - | [* black] We pick up the injection optics unit for a closer look. The lens within acts as a sorter, optically directing the mixed light into six individual tunnels in preparation for injection into corresponding waveguides (NEEDS WORK). |
| + | [* black] We pick up the injection optics unit for a closer look. The lenses within focus the projected light, directing it into six individual entrance gratings for corresponding waveguides. |
| + | [* icon_note] Looking really closely reveals the colors associated with each entrance grating: two red, two green, and two blue. |
