Abstract
Head-mountable devices can include adjustment mechanisms to achieve optimal alignment of optical components during and/or after assembly thereof within the head-mountable device. The alignment mechanisms can be integrated into the head-mountable device itself. A light projecting display element can be adjustable based on movement of ramp members within the head-mountable device (e.g., within an arm) to adjust an orientation of the light projecting display element relative to the waveguide onto which it projects light. Alignment can be verified based on the optical output of the display element. The adjustment mechanisms can adjust the display element during initial assembly and/or be operated by actuators that actively adjust the alignment as needed over time.
