Instruments and measurement techniques

• Acoustic emission analysis system with multi-channel transient recorder and calibrated resonant, multi-resonant and broadband acoustic emission sensors for locating micro-fractures

• Digital Image Correlation (DIC) using two 2.4 MPixel cameras and LED lights to detect displacement at surfaces due to cracking

• Eddy current: multi-frequency eddy current system for crack detection of metallic objects

• Inductive/capacitive instruments for measuring the rebar cover as well as conduit and defect tracking

• Infrared-­Thermography with a high resolution microbolometer camera and miniature camera; wide angle, macro and telephoto lenses, optically active excited Lockin-Thermography

• Moisture analyzer for the determination of concrete, screed and wood moisture; microwave measurements

• Network analyzer for calibration of measuring equipment and for ultrasound phase spectroscopy

• Radar with a 1600 MHz antenna, measuring wheel and laser position marks for profile measurements

• Radiographic training device with goniometer and different x-ray sources

• Simulation algorithms for modeling the propagation of elastic or electromagnetic waves

• Ultrasonic shear wave array with point-contact probes in transmission / reflection; tomography

• Ultrasound-Phased-Array for reflection measurements
