What is Thermal Imaging?

The air of paranoia that prevailed during the Cold War resulted in the emergence of thermography. The military began using thermographic devices for spying and other related activities. Towards the end of the 1950s, medical experts began to realise the value of thermography in the healthcare field. For instance, these experts found that some cancerous tissues emitted higher levels of heat than the tissues that surrounded them. This enabled healthcare experts to identify cancerous growth in the human body in a manner that was quicker and more reliable. During the intervening years, thermographic devices have become increasingly available for domestic and commercial use. Their increasing affordability has made them easier to procure for use in a myriad of ways.

Many people would have heard of drone thermal cameras. These devices harness thermographic principles for their functionality. For the uninitiated, thermal imaging refers to the process of detecting radiation (in the form of heat) from the infrared spectrum and converting it into an image. To illustrate how this process works in everyday life, consider a situation where an electrician installs sensors all over your property. Based on the images beamed by the sensors, you will be able to view your property with or without light. In recent times, the concept of thermal imaging has become particularly useful in the security industry. With crime rates increasing in many major cities, people are utilising technology for keeping their properties secure. As such, thermal imaging devices have become popular throughout the country.
