| [* black] After detaching the headband and inner faceplate, we have a better view of the eye-tracking IR emitters. We note they're all wired in series, rather than individually controlled. | |
| [* black] And finally, at our fingertips, the heart of the Magic Leap: a pair of [https://en.wikipedia.org/wiki/Field-sequential_color_system|field-sequential color (FSC)|new_window=true] LCOS microdisplays tasked with generating and projecting the images that the user eventually sees. | |

| + | [* black] As we noticed [guide|112245|earlier|stepid=214851|new_window=true], each lens contains six, layered waveguides. This allows a separate waveguide for each color (red, green, and blue) on two distinct focal planes. There are some unique advantages hidden in this stack of glass: |
| [* black] The three-waveguide-per-plane design corrects for the different refractive indices of each color. Without color-specific waveguides, [https://en.wikipedia.org/wiki/Chromatic_aberration|each color would focus to a slightly different point|new_window=true] and deform the image. | |
| [* black] Two focal planes allow the headset to layer images, and—by tracking the user’s eyes—decide which layer to bring into focus. This helps to create a sense of depth. | |
| [* icon_note] Overall, this approach is similar in principle to Microsoft's [https://en.wikipedia.org/wiki/Microsoft_HoloLens|HoloLens|new_window=true]—with an additional set of stacked waveguides—and closely follows some of Magic Leap's [https://www.kguttag.com/2018/03/01/magic-leap-new-patent-applications/|recent patent applications|new_window=true]. |
