About Us

 Quarktet was created to promote innovative and patented technologies that have been developed by Dr James Caron (Ph.D. Physics, University of Delaware). Originally, the company was created to market and license the patents. A demonstration program was created that would allow researchers to try SeDDaRA without having to do their own programming. After a couple of renovations, the program became quite functional and we started getting purchase requests. Our Tria Image Processing now boasts over 42 features and functions.Tria has even created a spin-off. PulseView is the first Data-Text-to-Graph (DT2G) program, enabling data files to be quickly displayed as graphs without spreadsheets, and is now available. University of Delaware Sharp Lab Sharp Lab at the University of Delaware

GCLAD was developed initially at the University of Delaware Center for Composite Materials to inspect composite materials during production. We sell the Dulcian photodetector that makes it work, being used by research groups in Florence, Italy, Aukland, New Zealand, and Kingston, Ontario. If requested, we can also build you your own "GCLAD-In-A-Box" ultrasound sensor. We are very appreciative of support we receive, especially from Research Support Instruments, where Dr. Caron remains as a full-time scientist. Additional supporters are listed on Links.

Quarktet is currently operated during non-standard working hours.However, with some after-hours effort and making use of modern technologies, we hope our partners and customers will find Quarktet as responsive and professional as a full-time company.The management team currently consists of Dr. Caron and Liz Dart Caron, who helped develop this website, and assists in design, management and financial operations.Tria Image Processing and PulseView programs were coded by Dr. Caron.

 Dr. Caron received his M.S. (1995) and Ph.D. (1997) in Physics from the University of Delaware, Newark, DE. During graduate study and post-doctorate work, Dr. Caron was the main researcher in the UD Laser Acoustics Lab giving him seven years experience in acoustics, optics, and electronics. He researched, designed, constructed, and operated the laser-based ultrasonic systems at UD. This includes designing and building photodetectors, servo circuits, filters, and amplifiers suitable for laser ultrasonics, operating and maintaining the Nd:YAG lasers, maintaining the laser ultrasonic system, and determining the course of the research. In this time, he invented Gas-coupled Laser Acoustic Detection. Through his work with Research Support Instruments, he developed unique image processing techniques, including SeDDaRA, and honed his programming skills.Both GCLAD and SeDDaRA are available for licensing. Check out our publications.

New to Quarktet?  This is a short description of our terms:

  • Laser Ultrasound--A class of techniques that generate or detect ultrasonic waves in materials using lasers.
  • CLGU--Continuous Laser Generation of Ultrasound.  This is a new method of generating ultrasound in materials using a high-powered continuous-wave laser.   
  • GCLAD--Gas-coupled Laser Acoustic Detection.  A method of detecting ultrasound where a laser's path is altered by the wave passing though the beam.
  • Dulcian--Our custom photodetector made specifically for GCLAD systems.
  • Blind Deconvolution--A class of methods that identify the blur in an image and attempt to remove the blur to restore the image.
  • SeDDaRA--A blind deconvolution method that identifies the blur in an image through comparison with a similar, but un-blurred image.
  • Tria--Our image processing progam that allows for easy application of SeDDaRA and host of other uncommon image processing methods.
  • ImPASS--Image Phase Alignment Super-Sampling--a method of combining a set of low resolution images into a single high resolution image.
