In celebration of our new patent, Tria is currently available at a reduced price, $320 (US).  In addition to our award-winning blind deconvolution, Tria has fast image registration, a good selection of de-noising filters, image analysis tools that cannot be found anywhere else, and great image viewers.  For Version 2.8, we have added five new filters, customized image math, improved line-outs, faster image opening, and faster batch processing.
Quarktet is proud to announce our latest release of PulseView,  version 1.4, available for only $24 (US)  We received such positive feedback from Tria's Line-Out graphs, that we created a 'spin-off'.  PulseView opens up text files and converts them to graphs, histograms, FFTs, and audio sound.  It is a simple idea that will save you a lot of time if you spend a lot of time graphing data files with spreadsheets or scripting programs.  See the PulseView page for more information.

We are now taking orders for 'GCLAD-IN-A-BOX', our low-cost, high sensitivity laser ultrasound detection system.   This system can be used for laboratory research, industrial proof-of-concept, or even customized to fit your application.  Our latest Dulcian detector (not pictured) has a remote optical housing for easier alignment and installation.  More information is available hereTurn-around time is about 6-8 weeks.

Our Story

Quarktet invents, develops, and markets innovative technologies to companies and corporations for mutual benefit, while also bringing select technologies direct to market. We seek collaborations, with both industry and academia, that will bring about further development and commercialization of our technologies. On this website, we are showcasing several promising technologies, SeDDaRA, GCLAD, and CLGU. This is also the only place for our great image processing software, Tria V2.8.09, a low-cost D2G (data-to-graph) program called PulseView v1.4, and a compact low-cost laser ultrasound detection system called GCLAD-In-A-Box.

Tria and the SeDDaRA method were featured in AstroPhoto Insight™ Magazine in April 2008.  AstroPhoto Insight is a bi-monthly digital  magazine dedicated to sharing the latest innovations and techniques in the field of cutting-edge amateur astrophotography.  Even without de-blurrring, many of their images are amazing!

SeDDaRA is a patented award-winning data restoration algorithm, that removes degradations from signals and images. The process is performed without prior knowledge of the degradation or detection system, a technique known as 'blind deconvolution'. The aberration is identified, cleaned, and removed from the original data.

For a classic example, Figure 1 is an image taken with the Hubble telescope before the optical correction was performed in 1993. The aberration was identified using SeDDaRA, and the image was restored using a pseudo-inverse filter. The result is shown in Figure 2. In addition to the planet and its rings being much sharper, stars in the background become apparent.

SeDDaRA has widespread applications ranging from improving medical images, restoring digital photography, and enhancing the frequency response of sound systems. What makes SeDDaRA so exciting is that it is easy to implement, easier to use, works in just a few seconds, and is amazingly effective. (See our new image processing software here.)

SeDDaRA, has been named as one of Advanced Imaging Magazine's Solutions of the Year for 2004! The solution won by unanimous decision for the removal of blur from an image of the background radiation of the universe. See the restoration and story in our Gallery. Read the press release here.

GCLAD is a laser-based microphone that has been used to record the human voice, musical instruments, and ultrasonic waveforms. In short, a laser beam is passed through a region where one wants to measure or record the acoustic changes. The sound waves create changes in the air's index of refraction. When the laser encounters these changes, the beam slightly deflects to a new course. This change is detected and converted to an electric signal by a custom-built photodetector. The basic setup is shown in Figure 3.

GCLAD has been used to ultrasonically scan materials in search of sub-surface defects. It has been used to record the human voice and musical instruments. GCLAD may find application as a high-tech microphone, scientific research tool, or as part of an ultrasonic imaging system.  Recent research now points to the way to miniaturization of the GCLAD system, which is now available for purchase.

Continuous laser generation of ultrasound (CLGU) is a newly patented method of producing laser generated acoustic wavefronts in materials.  A high-power continuous-wave laser is streamed across the target using a rotating mirror.  The fast scanning speed and thermal absorption produces an acoustic wavefront in the material.  This wavefront can be used to measure material strengths and sense material defects.  We have calculated that the scanning rate of CLGU is 20,000 times faster than ultrasound generation using pulsed lasers.
