Visualizing sound, acoustics and ultrasonics

Laser vibrometry enables non-contact vibration measurement and makes this technology the perfect tool for your audio and ultrasonic studies. Vibrometers are indispensable tools for you when you’re designing loudspeakers and identifying disturbing membrane resonances. Vibrometer measurements provide an experimental basis for challenging acoustic problems, such as predicting the structural-acoustic response, acoustic imaging, anti-sound and much more besides. Laser vibrometer measurements also prove beneficial in microphone, cell phone and hearing aid development. Most manufacturers of ultrasonic devices for industrial and medical use already place their trust in Polytec products for their research and development processes too. Its ability to reliably measure both actuators’ and sensors’ vibrational characteristics makes laser vibrometry an indispensable tool for FE modeling, optimization and troubleshooting.

Laser vibrometry focusing on the small details

Characterize small and delicate structures in a non-contact way. Analyze vibration, acoustics and dynamics. Measure biomedical samples, electronics components and microstructures like MEMS by light, without mass-loading, and from DC up to the GHz range on a large bandwidth. Laser vibrometers focus on the small details, measuring deflection shapes for model validation. They assess the frequency response and determine resonance frequency, impulse response and Q factor. No matter how big or small – Polytec vibrometers measure it!
