Scan & Paint 2D

Scan&Paint 2D is a tool to visualise stationary sound fields with an unmatched spatial resolution in full acoustic bandwidth. The system is a superb engineering tool for troubleshooting or benchmarking all kinds of objects on the spot. It only takes a few minutes to complete and entire measurement campaign. Results of the scan are translated by the software into a colour map, superimposed on a photograph of the measured object, allowing to find the origin of noise.

Scan&Paint 2D uses a simple and effective method for measuring time-stationary sound fields. The surface of the object being measured is scanned with a single PU probe, which is simultaneously captured by a camera. The recorded video and probe measurement data are automatically synchronised while the positions of the probe are extracted using live IR-LED tracking. This information is then used to produce acoustic imaging, which shows the origin of noise on the object. Microflown’s unique probe sensing technology allows you to achieve high-resolution imaging with a wide range of frequencies, even in challenging environments.

Getting you faster to your results, that’s what Microflown’s new real-time tracking feature offers you. The revamped Scan&Paint 2D includes state of the art technology: a new generation PU probe, and a revolutionary camera. The PU Regular GEN2 has two integrated IR LEDs that are invisible to the naked eye. When used in combination with an advanced camera, these LEDs enable real-time tracking of the probe’s position as it moves across the surface of the object being measured. Saving you valuable time, and allowing you to convert data into sound maps with a single click.
