The team is expected to carry the project from requirements through a demonstrated, documented prototype. The work includes, at minimum:
1. Work with ONTO Innovation engineers to understand the measurement objective, review the sponsor requirements, and flow them down into a complete set of system requirements.
2. Evaluate off-the-shelf scanning Fabry-Perot solutions and components against a custom design built from individual components, trading performance against the $2,500 material-cost target.
3. Design the optical cavity — including mirror selection, cavity length, finesse and free spectral range — and perform the supporting tolerance and alignment analysis.
4. Design the mechanical sensor housing and mounting, including any fiber or free-space interfaces, mechanical tolerance analysis, and an enclosed, compact package suitable for integration into a commercial interferometer.
5. Design the electrical subsystem: piezoelectric transducer drive electronics, photodiode sensing, digitization, and the processing solution.
6. Develop software to acquire, process, display, and record the transmission signal, and to determine longitudinal mode spacing.
7. Build the prototype and integrate the optical, mechanical, electrical, and software subsystems.
8. Test the assembled system against the sponsor requirements using the provided laser and iterate the design until performance targets are met.
9. Deliver documentation for alignment, operation, and calibration, along with design reports and test results, and present the completed system at Craig M. Berge Design Day.
