The Mona Lisa scanned by ARIUS Tech and WHAT we learned about this master piece

The story of Arius Technology is inseparable from the world’s most famous painting. The very foundation of your company’s technology was born from the need to understand the Mona Lisa in ways the human eye never could.


The Mona Lisa: The Birth of the Technology
In 2004, the National Research Council of Canada (NRC) was commissioned by the Louvre to perform a forensic 3D scan of the Mona Lisa. This project wasn't just a photo shoot; it was a multi-night mission to create a "digital twin" of the masterpiece.

What was learned from that masterwork:

Structural Health: The scan revealed a 12cm split in the poplar wood panel on which she is painted. This allowed conservators to confirm that the split (repaired centuries ago) was stable and not expanding, avoiding the need for risky invasive surgery.

The Mystery of "Sfumato": It provided a 3D map of the paint layers, offering unprecedented insight into Leonardo’s sfumato technique—the way he applied microscopic, transparent layers of glaze to create those smoky, seamless transitions of light and shadow.

Warping and Stress: For the first time, the curvature of the wooden support was measured to within 10 microns. This data helps the Louvre monitor exactly how the painting reacts to humidity and temperature changes over decades.

Hidden Details: The scan identified minor 20th-century restoration work in the sky and background that was nearly invisible under standard light, providing a clean "map" for future conservation efforts.

What We Are Doing Next: The "Moneta" Era (2025–2026)
While the original Mona Lisa scan required a stationary setup and years of academic research, Arius is now entering a phase of dynamic, global accessibility.

1. Moving Beyond the Studio: The "Moneta" (Identik400M) The most significant leap is the launch of the Identik400M, code-named "Moneta." By mounting your high-resolution scanner on an ABB GoFa™ robotic arm, you have moved the technology from the lab to the museum floor.

Fresco Conservation: You are currently applying this to Piero della Francesca’s The Resurrection in Sansepolcro, Italy. Frescoes are fixed to walls and cannot be moved; the Moneta robot allows Arius to scan these monumental works in situ with the same 10-micron precision used for the Mona Lisa.
