Yönäkökamerat

Yönäkökamerat, also known as night vision cameras, are electronic devices that allow for imaging in low-light conditions or complete darkness. They achieve this by amplifying ambient light or by using infrared illumination. There are two primary types of night vision technology: image intensification and thermal imaging. Image intensification systems work by gathering available light (starlight, moonlight, or even faint artificial light) and amplifying it, typically through a photocathode and a microchannel plate, to produce a visible image. These systems are often green-tinted due to the phosphors used in older technologies, though modern versions can produce black and white or even color images. Thermal imaging cameras, on the other hand, detect infrared radiation emitted by objects. All objects above absolute zero emit heat, and these cameras translate these temperature differences into a visible image, often displayed in false colors to highlight hot spots. Yönäkökamerat have diverse applications, including military and law enforcement surveillance, wildlife observation, security systems, automotive headlights, and in recreational activities like hunting and spelunking. Their effectiveness is measured in generations, with newer generations offering improved resolution, sensitivity, and reduced reliance on external light sources.
