IR technology in marine applications

The infra-red radiation was discovered in 1800 by English astronomer Sir Wiliam Hirchel but practical appl ications could be dated to the beginning of XX century. First advanced scientific investigations, as well as works relating to the military applications of IR technique were carried out during the First World War. Many applications of IR radiation exist until now. It is generally accepted that taking into account the destination the devices of IR techniques can be divided on three main groups: measuring devices, observation and aut omatic recognition systems. Devices of this type can be found both in Navy and civil marine.
