OPIR detects and characterizes radiant energy that is emitted or what?

• A. Absorbed
• B. Reflected
• C. Transmitted
• D. Scattered

Answer: (B)

The correct choice is reflected. OPIR, or Overhead Persistent Infrared, systems are designed to detect and characterize radiant energy emitted from various sources, including thermal emissions from objects. In addition to this primary function, these systems can also capture energy that is reflected off surfaces. When radiation from a source, such as the sun or artificial lighting, strikes an object, some of that energy gets reflected back into the environment. OPIR systems can pick up this reflected energy, providing valuable information about the object's characteristics, including temperature, material composition, and potential activity. This capability is particularly important for military applications, as it enhances surveillance, reconnaissance, and targeting by giving a clearer picture of the operational environment. Detecting reflected energy enriches the data provided by OPIR, allowing for better situational awareness. While the other options include forms of energy interaction, they do not directly represent the specific function of OPIR systems in the same way that reflected does.
