This is an infrared thermographic assessment on an aircraft
panel using an external cooling source (Active Thermography). The panel,
defected application of carbon epoxy composite patch on the metal
surface, was prepared by the Hellenic Aerospace Industry. Detection of
the defect & quantification of the defected area using histograms
was attained.
Thermographers:
Antonia Moropoulou, Nicolas P. Avdelidis (National Technical University
of Athens, Greece). |

"The
Collection" brings together the beauty of natural and infrared
butterflies. The round thermograms are showing the convex surface of a
heated hemispherical steel container. The thin wall of this container is
cooled from inside by flowing mercury. (SPIE Paper 4020-37, Thermosense
XXII, Session 5A)

This is an aerial infrared thermograph of a roof
showing crystal clear outlines (lighter areas) of subsurface moisture
contamination from 2000 ft. A.G.L. (Above Ground Level). No object in the images is detected via visible light
wavelengths (400-700 nanometers) rather, only from infrared wavelengths
in the 3000-5000 nanometers range.

High-speed infrared image of a brake rotor spinning at 60 mph on a
dynamometer with the brakes applied. This image shows several hot spots
that form around the rotor due to thermoelastic instability. This work
is detailed in Thermosense XX, page 66 and Thermosense XXII, page 2.

"Capturing Lightning in a Ceramic"
This is an IR image of a ceramic varistor 1 ms after electrical
breakdown caused by a high voltage pulse. The visible hot spots are due
to joule heating of the higher resistance grain boundaries. Note the
non-uniformity of the current through the varistor.
