Thermal imaging is a technology that converts infrared radiation (heat) into visible images, allowing users to detect variations in temperature that are invisible to the naked eye. Because it works in total darkness, smoke, haze, or fog, thermal imaging has become a critical tool across multiple industries. From defense and military operations to industrial inspections, healthcare, and building diagnostics, its applications are expanding rapidly.
The global thermal imaging market was valued at around USD 3.94 billion in 2024 and is expected to grow steadily, reaching USD 6.91 billion by 2033 at a CAGR of 6.17%. This growth is fueled by rising defense investments, technological advancements in sensors, and growing adoption in industrial monitoring and healthcare.
