A spot-like laser beam is collimated and deflected by mirrors to the
surface of a specimen.
Photoelectric transducers and a photodetector are employed to detect
and record location, size, and nature of surface flaws that are present on
the specimen as it is scanned.
The image is monitored through a TV camera, which also functions to
maintain the inspecting surface at a constant height.
The technology capitalizes on the known relationship
between surface condition and light diffraction patterns.
The patented techniques are adaptable to both
flat and undulating surfaces in a variety of non-destructive testing
applications such as:
Metal or glass sheets;
Electrical appliances and instruments;
CDs, diskettes, and semiconductor wafers.
The system may be tailored by altering the diameter and
number of optical fibers, as well as to accommodate specific situations
where high speeds may be required.
On April 1, 2001, Japanís
National Institute of Advanced Industrial Science and Technology began
operations as the "new" AIST.
The new AIST is a research organization that comprises
15 research institutes previously under the former Agency of Industrial
Science and Technology in the Ministry of International Trade and Industry
and the Weights and Measures Training Institute.
AIST is Japan's largest public research organization
with research facilities and more than 3,200 employees across Japan.
AIST is seeking to license these technologies and
assist with their commercialization success to qualified organizations.
Consideration will be provided to a range of financial,
strategic, and commercial investment options.
Certain circumstances will warrant consideration for modest
funding from AIST.
