Thermovision, also known as thermal imaging or infrared thermography, is a technology that detects and measures thermal radiation emitted by objects to create images based on temperature differences. It utilizes infrared cameras to visualize heat patterns, allowing for applications in various fields such as building inspections, medical diagnostics, and surveillance. By converting infrared radiation into visible images, thermovision helps identify issues like heat loss, electrical faults, and even medical conditions without physical contact.
