Labs and Equipment

Room 311, Earth Engineering Sciences Building
The Acoustic Microscopy Lab houses three acoustic microscopes for teaching and research:

1. The Ultran System for acoustic microscopy of large samples and low resolution (100 micron and up),
   
2. The Olympus UH-3 System for acoustic microscopy of small samples and high resolution (1 micron and up), and
   
3. The Ultrasonic Atomic Force Microscope U-AFM for acoustic microscopy of small samples and super resolution (10 nanometers and up).
   

These instruments are being used to investigate thin films, coatings, bio-cells, and semiconductors.

Georgios Maillis works on nuclear acoustic resonance for the detection of fissile materials.

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.

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.
