Image intensifier

An image intensifier is an optical device used to enhance the visibility of low-light images. It works by amplifying the light from a scene, allowing images to be visible in conditions where normal light would be insufficient for the human eye or standard cameras. Here’s how it typically works: 1. **Photon Capture**: The image intensifier has a photocathode, which is a surface that converts incoming photons (light particles) into electrons.
