1. Light Gathering: Night vision devices collect existing ambient light, such as moonlight or starlight.
2. Photocathode Conversion: Collected light passes through a photocathode, converting photons into electrons.
3. Electron Amplification: Electrons are accelerated across a voltage gradient, causing them to multiply significantly.
4. Phosphor Screen Conversion: The multiplied electrons strike a phosphor screen, causing it to emit visible light.
5. Image Magnification: The visible image is then optically magnified, providing a clearer and more detailed view.
