Thermal Imaging

  • A team of scientists from IIT-Bombay has now made a key breakthrough in developing India’s first infrared sensors for thermal imaging.
  • The research started in 2010, with funding from the Defence Research and Development Organisation (DRDO).
  • The technology, the scientists say, can be used for a range of applications such as night vision, surveillance and – going beyond military and security operations – even in the detection of cancers.
  • This will make the indigenous thermal imaging or night vision technology affordable and cheaper and will serve as a perfect example of Made In India.
  • This project could, perhaps, be the first significant development in the push for indigenous military equipment production.

Thermographic camera

  • It is also called an infrared camera or thermal imaging camera
  • It is a device that forms an image using infrared radiation, similar to a common camera that forms an image using visible light.
  • Instead of the 400-700 nanometre range of the visible light camera, infrared cameras operate in wavelengths as long as 14,000 nm (14 µm).
  • Their use is called thermography.
