BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infrared radiation amount control device that controls the amount of infrared radiation emitted from the outer surface of an aircraft or the like so as to be hardly detected by a partner infrared sensor.

く放射される。2. Description of the Related Art All objects having a temperature emit infrared light, and the amount of infrared radiation is uniquely determined by the temperature of the object and the infrared emissivity. The higher the temperature of the object and the higher the infrared emissivity, the more the amount of infrared radiation is radiated.

う。[0003] A large amount of infrared rays is radiated outward from the outer surface of a vehicle, a ship, an aircraft or the like due to heat generated by itself. Such vehicles, ships, aircraft, and the like are easily detected by an infrared sensor that detects infrared light. Therefore, it is easily detected and supplemented by a vehicle, a ship, an aircraft, a flying object, or the like equipped with the infrared sensor.

線放射量の差を少なくすればよい。In recent years, it has become quite common to equip vehicles, ships, aircrafts, flying objects, and the like with infrared sensors, and there has been an increasing demand for concealment of these infrared sensors. One of the effective measures for concealment is to reduce the difference between the amount of infrared radiation emitted by itself and the amount of infrared radiation emitted from the background. In particular, many infrared sensors having a sensitivity wavelength in the 3 to 5 μm band or the 8 to 14 μm band are used, and the difference in the amount of infrared radiation in both wavelength bands may be reduced.

As described in JP-A-209490, an infrared absorbing plate is arranged at a required distance from a heat source, and the absorbing plate is further cooled with water. These prior arts all suppress the amount of infrared radiation from a heat source.

６により外被１の温度を制御できる。In the infrared radiation amount control device configured as described above, under the control of the controller 6, heat is absorbed by the first heat absorbing and dissipating surface 3 of the Peltier element 2, and the heat is absorbed by the second heat absorbing and dissipating surface 4.
By dissipating the heat, the temperature of the first heat absorbing and dissipating surface 3 can be lowered. Conversely, if the heat is absorbed by the second heat absorbing and dissipating surface 4 and the heat is dissipated by the first heat absorbing and dissipating surface 3, the temperature of the first heat absorbing and dissipating surface 3 can be increased. In addition, since the first heat absorbing and dissipating surface 3 side and the second heat absorbing and dissipating surface 4 side of the Peltier element 2 are insulated by the heat insulating material 5, heat on one side can be transferred to the other without passing through the Peltier element 2. It does not reach the side. In addition, since the jacket 1 has a high thermal conductivity, a small heat capacity, and is in contact with the heat absorbing and dissipating surface 3 of the Peltier element 2, the temperature of the jacket 1 is close to the temperature of the heat absorbing and dissipating surface 3. Therefore, the temperature of the jacket 1 can be controlled by the controller 6.

り検知されにくくすることができる。The amount of infrared radiation radiated from an object is uniquely determined from the temperature of the object and the infrared emissivity. In addition, since the infrared emissivity is specific to the object, controlling the temperature of the object allows the infrared radiation to be emitted from the object. The amount of emitted infrared radiation can be controlled. Accordingly, the controller 6 estimates the amount of infrared radiation in the background from the temperature measured by the second thermometer 8, and the
The temperature of the jacket 1 can be measured and controlled by the first thermometer so that the amount of infrared radiation emitted from the outer surface becomes equal to the amount of infrared radiation emitted from the background. The outer surface of the jacket 1 is camouflage. Therefore, the vehicle and the like can be hardly detected by the visible sensor, the infrared sensor, the naked eye, and the like.
