A thermal imaging module is a core component integrated into devices like vehicle sights or surveillance systems, designed to detect infrared radiation emitted by objects and convert it into visible thermal images. For instance, the Ophelios-P module, housed in the R17A2 sight of upgraded Leopard 2 tanks, provides commanders with dedicated thermal targeting capabilities and enables video switching to share the gunner's view, significantly enhancing situational awareness in combat scenarios.

A thermal imaging scope is a standalone observation device widely used in military and security fields, allowing users to detect heat signatures of targets in total darkness, heavy fog, or other low-visibility conditions. Unlike basic night-vision scopes that rely on ambient light, it operates by capturing and amplifying infrared radiation, making it an invaluable tool for long-range surveillance, target acquisition, and perimeter security operations.
