Tria, Version
2.8, is now officially
available. 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 next
product, PulseView. 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 and FFTs. 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. More information
is on the PulseView page.

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. More
information is available
here. Turn-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 our two most promising
technologies, SeDDaRA and GCLAD. This
is also the only place for our great
image processing software, Tria V2.8.0, a
nifty D2G (data-to-graph) program
called PulseView,
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.

Hubble telescope before

and a pseudo-inverse

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.

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.

arrangement. A
light beam is

and sound
waves. A
custom-built
photodetector

deflection. |
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.

technologies, contact us and
we will discuss possibilities.
