Thermal imaging technology uses infrared radiation emitted from objects to generate images of them. A thermal imaging camera consists of an optic system, detector, amplifier, and display. There are cooled and uncooled cameras, with cooled providing better image quality but being bulkier and more expensive. Thermal imaging has applications in industry, medicine, security, and building diagnostics by allowing users to detect problems unseen to the naked eye. It provides advantages of being non-invasive and able to see in total darkness.

A sensor is a device that detects and responds to some type of input from the physical environment.
The specific input could be light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena.
The output is generally a signal that is converted to human-readable display at the sensor location or transmitted electronically over a network for reading or further processing.
Lidar (also written LIDAR, LiDAR or LADAR) is a remote sensing technology that measures distance by illuminating a target with a laser and analyzing the reflected light. Although thought by some to be an acronym of Light Detection And Ranging,[1] the term lidar was actually created as a portmanteau of "light" and "radar".[2][3] Lidar is popularly used as a technology to make high-resolution maps, with applications in geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, remote sensing, atmospheric physics,[4] airborne laser swath mapping (ALSM), laser altimetry, and contour mapping.
An automotive night vision system uses a thermographic camera to increase a driver's perception and seeing distance in darkness or poor weather beyond the reach of the vehicle's headlights. Such systems are offered as optional equipment on certain premium vehicles. The first introduction was in 2000 on Cadillac Deville.

3. INTRODUCTION
Thermal imaging is the technique of using the heat given off by an
object to produce an image of it or to locate it
First developed for military purposes in the late 1950s and 1960s by
Texas Instruments, Hughes Aircraft and Honeywell
In recent times it is being used in firefighting, law enforcement,
industrial applications, security, transportation, medical and many
other industries
4. THERMAL IMAGING
It is the technique of using the heat given off by an object to produce
an image of it .
Works in environments without any ambient light and can penetrate
obscurants such as smoke, fog and haze.
Normally grey scale in nature: black objects are cold, white objects
are hot and the depth of grey indicates variations between the two.
Some thermal cameras, however, add color to images to help users
identify objects at different temperatures
5. An image generated from a
Thermal Imaging Camera. Note
the persons skin (as a heat
source) is shown as ‘white hot’
whilst the sky (which is cold) is
shown as black.
7. THERMAL IMAGING CAMERA (TIC)
A thermal imaging camera records the intensity of radiation in the
infrared part of the electromagnetic spectrum and converts it to a
visible image.
8. WORKING OF THERMAL IMAGING CAMERA
A thermal imaging camera consists of five components: an optic
system, detector, amplifier, signal processing, and display
9. IMAGE PROCESSING
Image processing is any form of
signal processing for which the
input is an image, such as a
photograph or video frame and
the output may be either an
image or a set of
characteristics or parameters
related to the image
10. COMPONENTS OF THERMAL IMAGING

11. TYPES OF THERMAL IMAGING CAMERAS
COOLED THERMAL IMAGER
Cooled detectors are typically
contained in a vacuum-sealed case
and cryogenically cooled
Cooling is necessary for the
operation of the semiconductor
materials used else they would be
blinded by their own radiation
Cooled infrared cameras provide
superior image quality
Bulky and expensive to produce
and run
Cooling is power-hungry and time-
consuming hence the camera needs
time to cool down before it can
begin working again
UNCOOLED THERMAL IMAGER
Un-cooled detectors use a sensor
operating at ambient temperature,
or a sensor stabilized at room
temperature using control
elements
Resolution and image quality tend
to be lower than cooled detectors
Smaller and less costly to produce
and run
Fast operation and consumes less
power

14. THERMAL IMAGING IN INDUSTRIAL
APPLICATIONS
Whether you’re monitoring high voltage equipment, low voltage
cabinets, motors, pumps, high temperature equipment, looking for
insulation losses… A thermal imaging camera is the one tool that really
lets you SEE it all.
Electrical Systems
Low Voltage Installations
High Voltage Installations

18. THERMAL IMAGING IN MEDICINE
The technique essentially uses naturally emitted infrared radiation
from the skin surface.
The credibility and acceptance of thermal imaging in medicine is
subject to critical use of the technology and proper understanding of
thermal physiology.
Finally, we review established and evolving medical applications for
thermal imaging, including inflammatory diseases
Currently, there is interest in the use of thermal imaging for fever
screening

21. THERMAL IMAGING IN BORDER SECURITY
Due to their ability to detect man sized targets at extremely long
distances in total darkness and in extreme weather conditions thermal
imaging cameras are extremely suited for border surveillance.
Generally, cooled cameras are used in border security applications as
they provide a longer range performance than un-cooled detector.
If the terrain is e.g. mountainous and does not permit seeing over a
distance of 20 kilometers, un-cooled thermal imaging cameras can be
used for border security as well.
Thermal imaging cameras can be integrated with radar systems.
23. THERMAL IMAGING IN SECURITY AND LAW
ENFORCEMENT
With a thermal imager, an officer can stop and scan the property at a
distance, identifying any person present there.
Perimeter surveillance is another application in which thermal
imaging can be used to dramatically improve results and reduce the
time committed to a particular operation.
Thermal imaging cameras are also used in search and rescue
operations as officers may be able to search up to 1,500 feet in any
direction.

25. THERMAL IMAGING IN NIGHT VISION
Thermal imaging cameras are excellent tools for night vision.
They detect thermal radiation and do not need a source of
illumination.
They produce an image in the darkest of nights and can see through
light fog, rain and smoke.
Thermal imaging cameras are widely used to complement new or
existing security networks, and for night vision on aircraft, where they
are commonly referred to as "FLIR" (for "forward-looking infrared".)
27. THERMAL IMAGING IN BUILDING
DIAGNOSTICS
Thermal cameras show exactly where the problems are quickly and help
detecting energy waste, moisture and electrical issues in buildings.
Thermal imaging is used for maintenance of electrical, mechanical, and
structural systems, to detect problems, prevent downtime, guide corrective
action, and increase work safety.
Using thermal imagers it's easy to scan an entire building to detect building
envelope, and plumbing issues, presence of moisture in building envelopes,
either from leakage or condensation and water damage.

Chemical imaging
Volcanology
30. ADVANTAGES
Non-invasive and non-destructive hence can be used to survey whilst the
plant and equipment is running, in production and on load
Produces fast, accurate and immediate temperature measurement and
helps in fault detection
Cameras are easy to install and surveys can be performed at a convenient
time.
Is capable of catching moving targets in real time and in low light
conditions
Can be used to measure or observe subjects in areas inaccessible or
hazardous for other methods
Can help in identifying air leakages, documenting irregular heat
dispersion and identifying possible irregularities in insulation
Cameras can passively see all objects, regardless of ambient light.
31. LIMITATIONS
Quality cameras are expensive (often US$ 3,000 or more), cheaper are
only 40x40 up to 120x120 pixels.
Images can be difficult to interpret accurately when based upon
certain objects, specifically objects with erratic temperatures.
Accurate temperature measurements are hindered by differing
emissivities and reflections from other surfaces.
Most cameras have ±2% accuracy or worse in measurement of
temperature and are not as accurate as contact methods.
Only able to directly detect surface temperatures.
Thermal imaging cameras cannot be used to see objects under water
Because thermal energy can be reflected off shiny surfaces, thermal
imaging cameras cannot see through glass.
Also thermal imaging cameras cannot see through walls.
32. CONCLUSION
It deals with helping individuals see what the naked eye cannot.
However, helping you see even when there is no light is only a fraction
of what thermal imaging is used for. With the use of special cameras
and lenses, this technology offers benefits ranging from industrial
advantages, down to law enforcement.
