Night-Vision Goggles

The famous night-vision devices, although related to night vision devices, but they work, usually in the higher parts of the spectrum, and require that at least some coverage of some vneschnego or even infrared illuminator, so that this is not exactly what will be discussed. In the course of normal pitch darkness of night vision devices are not very much good, which, however, can not be said about working at low frequencies thermographic device. This type of devices capable of receiving termoizluchenie remote sites and convert it into visible images. so we can study the spectral traces of celestial bodies, or, for example, the temperature of passengers at airports during epidemics. A few years ago they were worth big money and is a very dimensional devices, today, these technologies have been proposed in the 'new package'. And they are suitable for mass use. Thermal radiation is produced by any object at a temperature above zero degrees Kelvin or -273 C. To visualize this radiation requires special equipment or infrared camera.

The American company Flir, known for its thermography techniques in the industry, offering consumer portable and very compact monochrome thermographic camera, designed for a wide range of uses, like power structures, the researchers studying the night life and even .. children! Of course how useful will Oonah kakzhdomu of the categories listed above question is quite controversial, but fairly clear one – 'toy' has been very entertaining. And who will find it application is another matter harakreta. The price of this device, however, even very 'grown-up – 3000 dollars. At the same time, it is much cheaper than the military designs of thermographic devices with approximately the same characteristics. We recall once more that the usual infrared radiation survey corresponds to a temperature between 250 C and 500 C, while the range of thermography is much more broad: from -50 C to over 2000 C.
