Last week, Ommatidia proudly sponsored and exhibited at the 1st International Conference on Experimental Continuation in Nonlinear Dynamics (XCON 2025). The event took place at the University of Liège and brought together experts in nonlinear structural dynamics. At XCON, our team showed how the Q2 Laser RADAR helps researchers test nonlinear systems with more precision and speed. Studying nonlinear vibrations is a challenge. Systems can show complex behavior that changes quickly. Traditional single-point sensors often cannot keep up. The Q2 offers a new way: 65+ laser beams in parallel provide full-field vibrometry in one shot. Non-contact interferometric sensing avoids errors caused by attaching sensors. Real-time Doppler vibrometry captures system dynamics as they happen. This allows researchers to perform response-controlled testing, bifurcation tracking, and branch exploration more reliably. During the live demo booth, attendees tested the Q2 with its latest features: These upgrades support adaptive testing strategies that rely on live vibration data. As a result, researchers can push beyond the limits of conventional methods. XCON also showed how academic research and industrial needs connect. The Q2 helps both groups by bringing photonics into structural dynamics. It speeds up discovery in labs and improves design validation in industry. We thank Prof. Gaetan Kerschen and the organizing committee for inviting us. We also thank everyone who joined our talk and visited our booth. The Q2 Laser RADAR is more than a measurement tool. It is a platform for advanced structural testing that supports the future of nonlinear dynamics research. For those who missed XCON: Explore the application, measurement approach and results behind this work. The University of Liège ORBi record identifies the International Conference on Experimental Continuation in Nonlinear Dynamics at the University of Liège on 28 and 29 August 2025. This page is therefore an archive of Ommatidia’s exhibit recap. a notice for an upcoming conference. Ommatidia’s first-party recap says it sponsored and exhibited at the conference and demonstrated Q2 multi-beam vibrometry. The university record independently confirms the event, dates and topic. Experimental continuation combines feedback control and continuation methods to trace nonlinear response branches, including responses that may be unstable without control. Synchronized velocity measurements at multiple locations can provide spatial response information to such a test.Ommatidia at XCON 2025: Multi-Beam Vibrometry for Nonlinear Dynamics
