What is a primary use of Thermal Imaging technology?

Thermal imaging technology is primarily used to detect infrared radiation emitted by objects, which allows it to visualize heat patterns. This capability makes it particularly useful in dark or challenging environments where visible light is insufficient or absent. By converting the heat signatures of objects into a visual format, thermal imaging can help to identify people, animals, or machinery in total darkness or obscured conditions, making it invaluable for search and rescue operations, surveillance, and various industrial applications.

The other options focus on functions that thermal imaging is not designed to address. For instance, enhancing light levels in bright environments, recording sound, or creating high-resolution color images in daylight do not pertain to the core function of thermal imaging technology. Instead, those tasks are better suited for different types of technology such as optical cameras or audio recording devices.
