these devices were manufactured just for the armed forces.

Infrared
Cameras are also known as thermographic cameras.
They are a valuable innovation in the field of photography. These
devices provide high-quality thermal imaging solutions on the basis
of infrared radiation. These images are required in fields like
astronomy and healthcare.

History
of thermographic technology

Infrared cameras
were first used during the Korean War. The reason behind this was
that they were extremely useful while fighting in the dark. These
cameras work on the basis of heat detection and thus they would be
used to identify the position of soldiers when they fought during the
night. In those days, these devices were manufactured just for the
armed forces.

While
equipment based on thermal imaging
is still extensively used for military operations, with changing
times infrared imaging is used in various fields like astronomy,
medicine, bio-conservation, archaeology, flame detection, and
firefighting.

Thermographic
equipment is used in wide range of medical procedures such as
oncology, breast thermography, and fever screening. FDA 510k Cleared
Medical Infrared Cameras, FDA 510k Medical Device Clearance are some
of the medical imaging devices used for acquiring high-quality
imaging solutions. These electronic devices are extra sensitive and
are used in the airports for detection of H1N1 viruses.

Often
these cameras are used by scientists or forest guards to keep track
of animals in the dark.

Types
of thermographic cameras

There
are two types of thermographic gadgets:
cooled
or uncooled. The cooled detectors come in vacuum sealed cases. This
is because the semiconductor materials like lead salenide, indium
antimonide, and mercury cadmium telluride need to be cooled to
extremely low temperatures in order to get proper images.

The
uncooled imaging devices operate in normal temperatures. Pyroelectric
and ferroelectric materials are used in this type of imaging
equipment. They do not need any type of cooling therefore do not have
vacuum sealed cases. This variety is more expensive than the cooled
ones.

The
following parameters are to be kept in mind while purchasing or using
these devices:

• Range

• Number
  of pixels

• Sensor
  lifetime

• Minimum
  resolvable temperature difference (MRTD)

• Input
  power

• Field
  of view

• Noise
  Equivalent Temperature Difference (NETD)

If
you want to have a unique experience in photography, buy an infrared
camera to
get a magical experience of thermal imaging. These are one of the
most sought after cameras in present times and may be ordered through
the websites of the manufacturers.
