Infrared Energy & Radiation
Part of electro magnetic spectrum
It travels through space at the speed
The thermal energy emitted from the
surface of a material is called IR
Temperature of an object=IR radiation
emitted from it.
Eg: x-ray, ultra violet, radio waves.
Infrared radiation, visible light & ultra violet
light form energy in spectrum.
Categorized by wave length & frequency.
Human eye can see narrow range of
It’s a - infrared imaging science.
- cost effective method.
- non invasive method.
- non contact method.
Applications include building diagnostics,
plant maintenance, research, etc.
IRT is the technique that used for
producing a visible image of invisible
IR energy emitted by objects.
Since wavelength is too long for the
sensors in our eyes, IR cameras are used.
Where it is used?
It can be applied in any situation
where a problem or condition can
display itself by means of a “thermal
For example, firefighters use it to see through smoke,
find persons, and localize hotspots of fires. Cooled IR
cameras can also be found at most major astronomy
What makes it useful?
Its non contact.
-uses remote sensing, keeps the user out of danger.
It is two dimensional.
-thermal patterns can be analyzed, comparison
between areas of target is possible.
It is real time.
-fast scanning of stationary targets, capture of fast
moving targets & fast changing thermal patterns.
Black body radiation-Black body is
that which absorbs completely all
the radiations falling on it.
The law is associated with “Thermodynamics”.
Every object whose surface temperature is above
absolute zero (-273 °C) radiates energy at a
wavelength corresponding to its surface temperature.
Produces a live TV image of heat
It converts invisible IR energy into
a 2d visual image & displays on std.
Thermal image produced is called
It allows us to see what our eyes can't.
It resembles a std. camcorder.
