Electrons enter holes in a micro channel plate (MCP) which generate more electrons. </li></ul><ul><li>. These multiplied electrons then bounce off of a phosphor screen which converts the electrons back into photons and lets you see an impressive night time view even when it's really dark. </li></ul>to collect and amplify infrared and visible light.

Thermal Imaging <ul><li>Thermal imaging technologies work by detecting the temperature difference between the background and the foreground objects. </li></ul><ul><li>A special lens(optics) focuses the infrared light. </li></ul><ul><li>The focused light is scanned infrared-detector elements </li></ul><ul><li>The detector elements create a very detailed temperature pattern called a thermogram(translated into electric impulses) </li></ul><ul><li>The impulses are sent to a signal-processing unit, that translates the information from the elements into data for the display. </li></ul><ul><li>The signal-processing unit sends the information to the display. </li></ul>

Continued…… It is quite easy to see everything during the day... Thermal imaging lets you see again. ... but at night, you can see very little.
