Proud to support future generations through our educational program

Do you want to prepare your students for the cutting-edge technology they will encounter in the industry? While many engineering disciplines involve the study of vibro-acoustics, the cost constraints mean that numerous school labs today are equipped only with basic accelerometers and microphones. Our PolyLab & PolyLab+ educational programs aim to bridge this gap, offering students the opportunity to familiarize themselves with state-of-the-art technology widely used in various industries.

PolyLab & PolyLab+ programs employ technology that goes beyond the limitations of traditional transducers. Vibrometers are indispensable for measuring on lightweight, very small structures, high-temperature surfaces, and underwater tests. Additionally, they can measure sub-picometer amplitudes and frequencies as high as 8 GHz.

Contact us to assess whether your institution qualifies for PolyLab or PolyLab+, and you may be eligible to receive free vibrometer loaners for educational purposes, ranging from 6 weeks up to 2 years.

What is PolyLab & PolyLab+

PolyLab/+ is a turn-key educational program that covers concepts such as vibration testing and modal parameters (natural frequency, damping, and mode shapes) and is accessible to students as an experimental framework. The PolyLab/+ kit contains a portable VibroGo® vibrometer, test objects and a lab tutorial with exciting experiments and relevant content. Students will enjoy working with the VibroGo® as it is easy to use and offers the possibility for fully digital non-contact vibration measurement, as well as analog data acquisition for visualization of transfer functions and much more. PolyLab is ideal for short term education needs for up to 6 weeks and PolyLab+ will provide continuous access to a VibroGo® laser vibrometer for up to 2 years.

PolyLab/+ contents

  1. The portable laser Doppler vibrometer VibroGo®, which measures real vibration behavior, acoustics and dynamics of excited structures in a non-contact and flexible way with a wide frequency bandwidth.
  2. Demonstrative experiments and practical tests in a detailed script for teaching vibration tests and measuring parameters such as resonance frequency, damping and deflection.
  3. Options for analog and digital data acquisition and analysis with Polytec VibSoft software.
  4. Additional: Support from our Polytec experts, including lectures showing the use of Laser Doppler vibrometer technology to solve important engineering tasks. In addition, practical examples of how the technology is used for a variety of applications (aerospace, microstructures, electronics, biomedical, ultrasound, etc...).

VibroGo highlights

  • Lightest, most compact vibrometer in a one-box solution
  • Built-in data recorder – no need for an external data acquisition system
  • Set up in minutes – no prior knowledge of vibrometry required, ideal in university environment
  • Dedicated tutorials and experiments to accompany the manual
  • Wireless settings change and data acquisition makes is a truly non-contact vibration measurement system
  • Form factor and easy set up makes it a perfect educational tool to explain fundamental concepts such as of non-contact vibration, acoustics, modal analysis, FE-model update, mass loading, data acquisition, excitation methods, damping, etc.

California State University

"Polytec's Laser Doppler Vibrometer PDV-100 was used by CSUN's Mechanical Engineering graduate students to perform experimental modal analyses on different laminated composite structures manufactured at CSUN's composites laboratory. Students were able to quickly run the tests and use the VibSoft software to obtain important structural parameters from the measurements. Students used the experimental data to update their computational models. All participating students reported that the LDV is very easy to use and the software is straight-forward. Students really enjoyed this hands-on project. Thank you so much Polytec! It was a nice learning experience."

Kettering University

"Kettering University physics and engineering students used the Polytec PDV-100 portable laser Doppler vibrometer kits as part of a unit on vibration and modal testing in our senior-level Acoustical Testing and Modeling course. Students were able to learn about the basic physics behind laser Doppler vibrometry, measure the vibrational modes of a cantilever beam, and compare measurements made using vibrometers with those made by accelerometers. We were also able to take measurements on vibrating objects that are hard to measure with accelerometers including a speaker cone and a guitar string. The availability of the portable laser vibrometers added a dimension to the course that we did not have previously and gives the students exposure to another technology useful in vibration studies."

North Dakota State University

"Mechanical engineering students from two courses at NDSU were brought together to perform structural dynamic analysis of a beam using the Laser Doppler Vibrometer (LDV) from Polytec's University Program (UP). They were able to calculate Young's modulus and second moment of inertia of the cross section. Students were also able to calibrate the piezoelectric accelerometers and compare their calibration results to those recommended by the respective manufacturers. In both cases, students were amazed on how their experimental results agreed with expected theoretical results, which is highly credited to the accuracy offered by this LDV unit. We really thank Polytec for allowing us to use the UP units in our labs as it has tremendously enhanced our course delivery."

Stanford University

"Stanford University’s Center for Computer Research in Music and Acoustics (CCRMA) used a Polytec Portable Digital Vibrometer (PDV-100) to study the acoustics of musical instruments. The vibrometer allowed researchers to capture the vibrational characteristics of individual acoustic and electric guitars. The vibration measurements serve as the basis for computational models which are used to study the acoustics of the instruments as well as to produce sound synthesis for music making."

The study was led by Chris Chafe, Director of CCRMA at Stanford University.

White Noise, LLC

"The VibroGo sensor was an important asset to my introduction to NVH engineering at Waterloo Christian.  For the vibration demo I magnetically attached a speaker to a small fuse box.  The speaker was fed a swept sine and the box vibration was measured with an accelerometer and the laser.  A mic recorded the sound.  One thing that was fun to demonstrate was playing back the accel and laser signals through the Dewe’s sound system and then demonstrating reciprocity by speaking into the box and again playing back the sound to hear what was said."

University of Iowa

"The portable Laser Doppler Vibrometer VibroGo system, on loan from Polytec, allowed us to establish feasibility and collect preliminary results for a grant application. The system allowed us to distinguish important effects of fruit fly mutations on active hearing by measuring displacement or velocity of their antennae. The portable system also opens the potential for us to incorporate it as a tool in our undergraduate Animal Behavior Laboratory class to measure stridulatory behavior or acoustic function in insects. Vibrometry data would add significantly to opportunities for our students to develop quantitative understanding of animal behavior. We appreciate Polytec’s generosity in allowing us to learn and use this robust and well-designed instrument."
