The principle of operation of the device (invention) is as follows.

The first method of educational experiment.

The thermometer fixed in a tripod is a simulator of the eye of a biological object that does not use any means of protecting the organs of vision. The temperature, which is a pain threshold for the human eye, is in the range from 40°C to 44°C. The thermometer of this model (Thermoval Rapid) allows you to measure temperatures, including in this range.

When a laser fixed in another stand is activated, the radiation emanating from it passes through a device to simulate weather conditions and enters a thermometer sensor made of stainless steel, with a density of 7640-7670 kg / m ³ , gradually heating it. After some time, the temperature begins to rise, which can be clearly seen on the electronic display of the thermometer in real time.

The second method of educational experiment.

The sensor of the laser radiation current-voltage characteristic meter (meter) located on the stand is a photocell of the solar battery, it is also a laser radiation absorber and a screen.

When the laser fixed in the tripod is activated, the radiation passes through the device to simulate weather conditions and enters the sensor of the meter, and the electronic display of the meter, which is a multimeter (DT-830 DIGITAL MULTIMETER), displays the numerical values of voltage and current in real time.

In the first and second methods of educational experiments, measurements are carried out at different distances up to a maximum of 1 meter of the measuring ruler.

Both in the first and second methods of training experiments, using a device to simulate weather conditions, the following is simulated: rain from a spray device, fog (steam, aerosol) using a device for thermal sublimation of mixtures, which is distributed in the volume of the chamber (glass container), through which and passes the laser light.

In addition, in the first and second methods of training experiments, instead of or after the device for simulating weather conditions, various protective materials are placed on the second stand and measurements are taken using a set of measuring devices.

In the future, the obtained values are processed using an electronic computer (computer), which is not included in the device, to carry out the necessary calculations and draw conclusions about the effectiveness of protection against laser radiation.

Description of the device. The device consists of a number of interconnected main technical devices included in it, such as a simple laser weapon simulator, a device for simulating weather conditions, a set of meters for the characteristics of the simulator and protection against its effects.

The assembled device is compact, weighs 2.5 kg, can be carried by one person in any suitable size package, easy to use and economical. The cost of technical devices included in its composition is about five thousand rubles, excluding the cost of a computer that is not part of the device.
