The Technology of Night Vision
Through succeeding generations, image intensifying devices have brought vision to the dark of night. Image intensification, the basis of night vision, is a complex conversion of energy particles that occurs within a vacuum tube. An image-intensifier system works by collecting photons through an objective lens, converting them to electrons via a photocathode, increasing the electrical energy with a microchannel plate (MCP), converting the electrical energy back to light using a phosphor screen...
