Ensuring Integrity in Eye-Tracking VCSEL/LED Manufacturing

In modern infrastructure, where cameras, sensors, and illumination systems play a vital role in automation and safety, precise radiometric evaluation of eye-tracking VCSELs and LEDs is essential to identify faulty or degraded devices. Fairbuild has developed a dedicated quality evaluation test suite engineered for high-throughput manufacturing lines, enabling our enterprise customers to scale confidently while advancing next-generation technologies.

To ensure test integrity and security, we employ encryption and digital signatures on all production log files. This allows customers to perform periodic integrity checks, ensuring that any unauthorized modifications to test configurations, limits, or results are immediately flagged — safeguarding the reliability of your production process from end to end.

Fairbuild monitors the latest advances in accurate sub-pixel resolution corner detection and pairwise checkerboard detection solutions along with optimization procedures and initial parameter approximations that provide robust and fast convergence for high volume camera manufacturing.

Our camera calibration can be used to monitor multi-camera placement and their relative alignment camera array systems. Fairbuild has provided a custom camera calibration solutions for autonomous driving assistance cameras in automotive market.

Precision Optical Quality Evaluation with Circle SFR®

Fairbuild’s Circle SFR® enables precise comparison of sagittal and tangential spatial frequency response (SFR) measurements against optical simulation results—offering deep insight into lens and camera assembly quality. Deviations or tilt in the measured MTF surfaces may reveal potential misalignment between the lens and image sensor, allowing early detection of build issues.

For camera and display manufacturers, we offer licensing of the Circle SFR® production binary, built to deliver fast, reliable, and simulation-aligned optical analysis on the factory floor. Having undergone multiple refinements in high-volume environments, Circle SFR® is optimized for robustness, throughput, and real-time execution in demanding production settings.
