Apparatus for monitoring hot waste water discharged from power plant by using airborne multispectral scanner system

An apparatus for monitoring hot waste water discharged from a power plant by using an airborne multispectral scanner system, the apparatus comprising:

• a first detector comprising a first image data collecting unit to obtain first image data by collecting a data image, which is introduced through an opening and reflected by a scanning reflector having a motor attached thereto, onto a paraboloidal reflector, and a liquid-phase nitrogen storing tank used to cool an image obtaining sensor;
• a second detector comprising a second image data collecting unit to obtain second image data by collecting the data image, which is introduced through an opening and reflected by the scanning reflector having a motor attached thereto, onto a paraboloidal reflector, and a liquid-phase nitrogen storing tank used to cool an image obtaining sensor;
• a controller to process the first and second image data obtained by the first detector and the second detector, respectively;
• and
• an auxiliary liquid-phase nitrogen tank separated from the liquid-phase nitrogen storing tank.
