China Review News (CRN) recently reported that the People’s Liberation Army (PLA) has developed night vision maps. Last year, the PLA started searching for practical night vision technology for maps. The University of Lanzhou, the Map Institute of Gansu Province, and the Surveying and Mapping Institute of the PLA General Staff Department jointly worked on the project. The night vision maps emit “cold light” which can only be seen by people nearby; remote enemies cannot see them, even with today’s military night vision equipment. The technology used to print the maps enables them to preserve energy in daylight. They are waterproof, radiation-free, and have good luminous intensity. The material is suitable for mass production.
