The waveguides may be located between outer lens elements and inner lens elements. Flexures may be used to attach the waveguides to the head-mounted support structure. The flexures may include two or more rings that are welded together to form two or more springs. The springs may allow the waveguides to move relative to the head-mounted support structure when a force is applied to the head-mounted structure, thereby preventing deformation of the waveguides. An elastomeric stress attenuator may be interposed between the waveguides and the support structure to absorb impacts that would otherwise damage the waveguides.

Electronic Devices With Gaze Trackers

A head-mounted device may include a housing having openings that receive lenses. Displays may output images. Waveguides that overlap the lenses may receive the images from the displays and may direct the images to eye boxes that are aligned with the lenses. Infrared light sources such as infrared light-emitting diodes or lasers may be used to supply infrared light to the waveguides. Each waveguide may have multiple localized output couplers that overlap the lenses. The localized output couplers of each lens each direct a beam of the infrared light out of the waveguide towards an eye surface in the eye box associated with that lens to produce an eye glint. A gaze tracker infrared camera may captured images of the eye glints to determine a user's point of gaze.

Device Alignment Systems

A head-mounted device may have display projectors that provide images. Waveguides may be used in conveying the images to eye boxes. Optical couplers such as prisms may be used to couple the images from the projectors into the waveguides. The waveguides may guide the images to output couplers that couple the images toward eye boxes for viewing by a user. During operation of the head-mounted device, sensor circuitry may be used to measure for potential misalignment between optical components such as projectors, couplers, and waveguides. Control circuitry may provide control commands to zero hold power piezoelectric actuators or other positioners based on the sensor measurements, thereby tilting and otherwise repositioning the optical components relative to each other to correct for optical component misalignment.
