Thermal imagers in military and civil engineering

April 19 2012 2

The device used to differentiate temperature levels in a specific area is called a thermal imager. As you know, any object with a positive temperature is a source of certain signals of electromagnetic radiation. In this case, considered infrared radiation emanating from a silt of another object. Modern thermal imager allows you to calculate the intensity of this kind of radiation, to determine the temperature characteristics, as well as to easily calculate and transmit the coordinates of the source of infrared radiation. In this case, any digital indicators of thermal imagers can translate into a graphic canvas, by which one can judge the most different characteristics of the object.

Such properties of thermal imagers are successfully used in military technology. Thermographic picture can tell the operator of the thermal imager both about the location of the target, and about its size and a number of other parameters.

Thermal imaging equipment is used in aviation. For example, an EVS3 onboard thermal imager from FLIR SYSTEMS, with its rather miniature size, can significantly help the pilot both in controlling the aircraft and in hitting a target. Such a thermal imaging camera easily detects almost any object through a thick veil of fog. This aircraft equipment will detect any obstacle on the runway using infrared sensors and transmit a signal to the pilot.

By the way, thermal cameras today are actively used on amphibious aircraft Be-200. Even at high altitude, the camera is able to catch even a small source of fire. With the help of thermal imaging sensors, you can map the fires on a specific area and make a conclusion about the fire fighting strategy in this area. This allows you to repeatedly reduce the cost of new water intakes from reservoirs, and hence, put out the fire much faster.

A thermal imager on a military aircraft or helicopter allows you to catch a target in the infrared wavelength range and deliver a point impact even in absolute darkness or thick fog that interferes with the visual overview of the terrain.

Today, in various forums you can find "tips" on how to resist the thermal imagers of aircraft. However, any "advice" once again proves that in fact the effective protection of the target from its all-seeing eye has not yet been invented, unless, of course, serious ways to "pour yourself with liquid nitrogen” are considered ... ”
