Hi !!!

Mi Community
I am back with yet another informative yet exciting post, This time we will dive into the world of Thermography.
Get ready and see the magic unfold.

Introduction
Our human eye can see visible light or small part of electromagnetic spectrum. Human eye cannot see any types of radiation like ultraviolet light or infrared light. Infrared energy is just one part of the electromagnetic spectrum that encompasses radiation from x-rays, gamma rays, ultra violet, and a thin region of visible light, radio waves infrared, and microwaves. By the help of thermogaphic camera, we can determine the temperature of an object, infrared radiation is used. So today we will know about Thermal imaging or Thermographic camera.

What is Thermography?


Infrared thermography technique uses an infrared imaging to detect, display thermal patterns and temperature across the surface of an object. Thermography can be applied to any situation where any types of thermal temperature will provide meaning data about a system or object. It is that types of equipment which senses infrared radiation by converting it into temperature and displays image of temperature distribution

How Does Thermal Imaging Work?


  • The main function of Thermal cameras is to detect temperature by recognizing and capturing different levels of infrared light. This types light is invisible that our naked eye can't see, but can be felt as heat if the intensity is high enough.
  • Almost all object except some kind of infrared radiation, and it’s one of the ways that heat is transferred. If you hold your hand over some hot coals on the grill, those coals are emitting a ton of infrared radiation, and the heat is transferring to your hand. Furthermore, about half of the sun’s energy is ultravoilet and infrared light.
  • Thermal cameras can see this heat and convert it to an image which we can then see with our eyes, almost like a night vision camera which capture invisible light and convert it to an image.

How Thermal Imaging Camera Works?


Let us understand working of thermal imaging camera.
  • Infrared energy coming from object is focused by optics onto an infrared detector.
  • The detector sends this received information to sensor for image processing using complex algorithms.
  • The sensor translates this data into an image which can be viewed on LCD screen of the thermal imaging camera.
  • Each pixel of image is measure of temperature at different points. For example if resolution of image by camera is 60 x 60 pixels, then it is equivalent to use of about 3600 Infrared thermometers used simultaneously.

Advantages Of Thermal Imaging


Following are the benefits or advantages of Thermal Imaging:
  • This technology has created more efficient and safer method of measurement.
  • Regular predictive maintenance using thermal imaging products help in saving money and consecutively lower the costs. This is due to less downtime, power outages, production losses, fires etc.
  • Thermal imaging products provide fast and accurate measurements of objects which are difficult to touch/to reach such as high altitude power lines.
  • Thermal imaging allows very accurate temperature measurements of machines from distance and in running condition as shown in the figure-2. This running machines are very hot and dangerous to contact. Moreover it can not be turned off until production is completed.
  • It can help in identifying air leakages, documenting irregular heat dispersion and identifying possible irregularities in insulation.

Conclusion


Thermography is the way to see and measure heat. This procedure is used thermal image for display,detect thermal patterns and temperatures across the surface of an object. In this thread, we know the principle of thermography and how thermal image is processed in camera via optical system, thermal detectors, scanning mechanism and display. In future, the focus on infrared thermography should be on more sensitive and fast IR cameras together with powerful computers that make us possible to manage even more complex and efficient algorithms and larger data matrices. So this is the conclusion of Thermography along with their advantages and disadvantages.
