Engineering experience
01Wearables + near-eye display
Near-eye display optical platforms
PAO engineering leadership experience connecting near-eye optical architecture, module specifications, tolerancing, prototype bring-up, and supplier transfer for AR display hardware.
Attribution boundary
This record describes work performed by PAO engineering leadership in a prior role. It is not a PAO customer case study and does not claim a prior employer's commercial or product-performance results.
01Program context
A system problem, not an isolated optical component.
Compact display systems force the optical engine, waveguide or combiner, mechanical datums, electronics, calibration, and human viewing geometry into one tightly coupled package. The work is less about optimizing a single lens and more about controlling the interfaces that determine the viewed image.
Engineering leadership role
In prior optical-leadership roles, PAO engineering leadership worked on near-eye display architecture, optical-module requirements, tolerance control, prototype bring-up, supplier qualification, and coordination between US engineering and Asia-based manufacturing resources.
02System frame
The interfaces that had to work together.
Relay
Collimation, pupil formation, field mapping, and aberration control
Combiner
Waveguide or see-through interface, efficiency, color, and eyebox behavior
Product
Datums, fit, thermal stability, calibration, and repeatable assembly
03Engineering scope
Responsibilities that transfer to new development work.
Near-eye display and optical-engine architecture
Eyebox, pupil, field, image-quality, and packaging trade studies
Module specifications, tolerances, and mechanical interfaces
Prototype bring-up, calibration planning, and fault isolation
Supplier qualification and design transfer
04Engineering decisions
Where system judgment mattered.
Allocate performance at system level
Field of view, eyebox, eye relief, resolution, distortion, efficiency, and package volume compete with one another. A useful architecture makes those trades explicit before component commitments lock the design.
Treat datums and calibration as optical elements
The observed image depends on how the optical engine, combiner, frame, and user's eye are registered. Mechanical datum strategy and calibration provisions belong in the optical error budget.
Design transfer before design release
Supplier capability, measurement method, assembly sequence, and adjustment strategy should be understood while tolerances are still negotiable, not after drawings are complete.
05Engineering outputs
Work products, stated without invented metrics.
Optical architecture and interface definitions
Module-level requirements and tolerance budgets
Prototype bring-up and calibration plans
Supplier technical reviews and acceptance criteria
Transfer documentation for repeatable integration
06Transferable lessons
What this experience changes in the next program.
The best optical prescription is not useful if the package cannot hold its pupil and line-of-sight relationships.
Near-eye image quality should be reviewed across the usable eyebox, not only at one nominal eye position.
Prototype measurements must distinguish optical limitations from alignment, display drive, calibration, and observer effects.
07Evidence + limits
What supports this record, and what it does not claim.
Supporting records are available during technical qualification. Documented scope is labeled separately, and publication limits are retained so the record remains credible without exposing personal identity or confidential details.
Prior-role records cover an AR imaging display system involving an optical-engine module and waveguide structure. Supporting details can be reviewed during technical qualification.
Product-specific performance, supplier identity, production volume, and confidential implementation details are intentionally omitted.
