How did the first night vision goggles work?

The first night vision goggles, developed during World War II, utilized an early image intensification process to function effectively. The core principle behind these goggles was the conversion of invisible infrared light into visible light, enabling the wearer to see in the dark.
The process begins with a photocathode inside the goggles that absorbs incoming photons from the ambient light or infrared radiation. These photons strike the photocathode, liberating electrons in the process. The electrons are then accelerated and focused by an electric field, resulting in a cascade of more electrons, greatly amplifying the original signal.
Once the electron cascade reaches a phosphor screen, it releases a burst of visible light, creating a green-hued image for the viewer to see. The green color was chosen because human eyes are more sensitive to green light, making the images easier to perceive and less likely to cause eye fatigue during extended use.
