-[* black] Turning our attention back to the motherboard, we pluck an unidentified component from below the camera bracket.
-[* black] This is likely the IR rangefinder that drives the 2's laser autofocus system.
+[* black] While we're on the topic of imaging, here's one last component that makes up the OnePlus 2's fancy photographer: The infrared laser rangefinder.
+[* black] Comprised of a focused IR LED and an IR receiver, this component likely works by projecting a cone of IR light on the subject, and then measuring the width of the projected light with the receiver. This would allow it to estimate the distance to the subject, and snap to the right focus distance faster.
