Editor's Notes
- #2 Watch this video to get a better understanding of how night vision works.
- #3 Night Vision had revolutionized the warfare in the past 20 years. Ask student what recent war’s used night vision.Answers: Desert Storm, Iraq, and others. We are going to talk about how night vision works and it other uses besides warfare.
- #4 An Image is viewed through the objective lens. The image is inverted in the image intensifier. While in the Image intensifier the image protons is passed through the Photocathode then is converted into electrons. Once electrons the image is passed through the MicroChannel Plate and the where the electrons are Multiplied. The Multiplied electrons are passed through the phosphor screnn and reconverted into photons. Once Converted onto Photons the images is brought into the Collimator, please not the the image is still backwards once passed through the Collimotor it hit an angled Mirror and then another mirror, in this process the image is then flipped and now can be viewable through the eye piece.
