Labs and Equipment
Acoustic Microscopy Lab
Room 311, Earth Engineering Sciences Building
The Acoustic Microscopy Lab houses three acoustic microscopes for teaching and research:
- The Ultran System for acoustic microscopy of large samples and low resolution (100 micron and up),
- The Olympus UH-3 System for acoustic microscopy of small samples and high resolution (1 micron and up), and
- The Ultrasonic Atomic Force Microscope U-AFM for acoustic microscopy of small samples and super resolution (10 nanometers and up).
Room 310, Earth Engineering Sciences Building
The Acousto-Optics Lab features the Microscopic Electronic Speckle Pattern Interferometer (MESPI) for measuring holographically the dynamic surface deformation (0.1 micron resolution) in-situ. For example, during laser drilling and cutting surface deformation results from thermal stress. Another feature instrument is a system for the detection of cracks in locomotive wheel tires with the use of electromagnetic acoustic transducers (EMATs).
Brad Bond works with the Microscopic Electronic Speckle Pattern Interferometery (MESPI) system.
Nondestructive Evaluation Teaching Lab
Room 406, Earth Engineering Sciences Building
The Nondestructive Evaluation Teaching Lab features an X-ray instrument and an acoustic emission system. These instruments are part of the lab hands-on demonstrations for the EMch/MatSci 440 course: Survey of NDE Techniques.
