Fundamental Principles of Infrared and Ultraviolet Sensors in Reconnaissance
Infrared and ultraviolet sensors operate based on their ability to detect electromagnetic radiation within specific wavelength ranges. Infrared sensors sense thermal radiation emitted by objects, allowing visualization of heat signatures in low-light conditions. Ultraviolet sensors detect short-wavelength radiation, often resulting from fluorescence or absorption phenomena.
These sensors utilize specialized materials and photodetectors that respond selectively to IR or UV radiation. Infrared sensors typically employ materials like indium antimonide or mercury cadmium telluride, while ultraviolet sensors often use semiconductors such as gallium nitride.
