Research
In Development
  • The Tria Image Processing Program is now availalbe for 64-bit machines as a 64-bit program.  Processing speeds are up, and errors are down.
  • GCLAD was presented at the First International Symposium on Laser Ultrasonics, 2008.  See the reference below.
  • A new GCLAD detector is now in development and will be available for sale.  We are also working on a new laser-based  ultrasound generation method.

    As you may have noticed, the development of these technologies was greatly accelerated by the advisement and research of my colleagues at the University of Delaware, Research Support Instruments, the Naval Research Laboratory, and Catholic University of America. 

    Thank you all
