What is Thermal Imaging Technology?

Thermal imaging, also known as infrared thermography, involves capturing images based on the infrared radiation emitted by objects. Since all objects above absolute zero (-273.15°C) emit infrared radiation, thermal imaging devices detect this radiation and convert it into a visual representation, known as a thermogram.

Key components of a thermal imaging system include:

  1. Infrared Sensors: Detect heat radiation and measure temperature differences.
  2. Lenses: Focus infrared radiation onto the detector.
  3. Signal Processing Units: Translate infrared data into readable images.
  4. Display Systems: Present thermograms to the user in real time.
