Beschreibung
Zusammenfassung:	An optical assembly to be used in a head-mounted display (HMD) device or similar may include a first optical component and a second optical component, where the first optical component and the second optical component are layered in the optical assembly. The optical assembly may also include a waveguide positioned between the first optical component and the second optical component. One or more shock absorbers may be positioned on surfaces of the first optical component and the second optical component facing the waveguide. The shock absorbers may be a support that touches a surface of the waveguide or a stand-off that extends toward the waveguide with a gap. The shock absorbers may also include a pillar, a cone, an inverted cone, an inverted pillar, a spring, a double helix, a three-dimensional mesh, a strap, a bumper, a sphere, or a high aspect ratio 3D mesh tower.
