Tools for the Future of Automotive Vision


At Photonics West 2025, Fourier Image Lab and our partners at Yanding were proud to present a unified vision for the future of automotive imaging — one that focuses on measurability, repeatability, and scalability.


Modern imaging systems for ADAS and autonomous vehicles face increasing demands, not only in perception performance but also in how well they’re benchmarked, calibrated, and integrated. During the show, we showcased three cornerstone tools — each designed to rigorously evaluate and optimize a critical aspect of automotive vision.


1. Resolution, Focus, Alignment, and Distortion


Our RFT system brings automation and precision to the task of measuring optical performance. With its robotic alignment and programmable lens testing setup, it provides accurate characterization of:

  • Resolution (MTF) across the field of view

  • Focal sharpness and depth-of-field behavior

  • Geometric distortion and boresight alignment

This tool is invaluable for benchmarking lens quality, detecting subassembly inconsistencies, and ensuring long-term manufacturing stability.

2. Dynamic Range and Field Uniformity Benchmarking


Evaluating dynamic range isn't just about measuring black and white — it’s about understanding how a sensor responds to complex transitions in light, contrast, and tone. At Photonics West, we demonstrated two ultra-bright lightboxes.


One lightbox was paired with our 150 dB HDR dynamic range chart, allowing us to showcase how sensors handle extreme contrast scenarios — from deep shadows to saturated highlights — in a single frame. The other lightbox featured our Radial Frequency Response (RFR) chart, a tool designed to visualize how resolution and sharpness vary at different angles, revealing lens or sensor inconsistencies often missed by conventional MTF charts.


Together with our integrating sphere, these setups provided a comprehensive environment to evaluate:

3. Color Accuracy and Spectral Response


Our Multispectral Light Booth was also on display — capable of replicating real-world spectral environments from sunlight to LED to industrial lighting. With up to 32 independently controlled LED channels and closed-loop feedback using integrated spectrometers, this tool supports:

  • color matrix evaluation and white balance tuning

  • spectral response modeling

  • visual consistency checks across different lighting conditions

A Growing Team with a Shared Vision


Photonics West wasn’t just a showcase of tools — it was also a celebration of a growing collaboration between Fourier Image Lab and Yanding. Together, we continue to bridge advanced lab technologies with the needs of real-world perception systems.

Our mission is simple: to provide rigorous, production-ready testing systems that help imaging teams build smarter, safer, and more consistent vision solutions. Whether you’re tuning lenses, optimizing color pipelines, or validating HDR performance, we’re building the infrastructure that turns theory into trusted results.


All of the tools presented above — along with additional testing and calibration systems — are now fully deployed and operational at our new facility in Campbell, California.
