RU2621223C1 - Method of non-lethal laser effect on the violator - Google Patents

Abstract

FIELD: physics.

SUBSTANCE: violator exercise with an impact pulse where laser beam with variable frequency impulses and their duration, with laser radiation impact zone further expose an incoherent white light. Using a combination of changes in frequency and duration of pulses makes it possible to form a persistent psychophysiological reaction avoiding the zone of exposure.

EFFECT: use of incoherent white light reduces the likelihood of irreversible loss of sight by the violator.

Description

The invention relates to techniques for non-lethal laser exposure of intruders and can be used in physical protection systems of objects.

Known laser rifle PYASR [1] and a laser gun [2]. The disadvantage of these samples is that their use at close range causes irreversible loss of vision. When the optical properties of the air (rain, fog) change, the efficiency sharply decreases due to the continuity of laser radiation, the availability of an effective low-cost protection method using widespread laser goggles, and quick adaptation of the eyes to continuous laser radiation.

Closest to the claimed invention is a mobile single-beam laser unit ZM-87 [3], using pulsed radiation with a frequency of 5 flashes per second.

The disadvantage of this installation is its short range due to the dispersion of the laser beam on water vapor and dust contained in the air. An increase in range due to an increase in power is not possible due to international restrictions on the permissible radiation level. The eyes of the intruder also adapt to the pulsed action with constant parameters (pulse duration and frequency).

The technical result of the invention is to increase the range through the use of a pulse-modulated laser beam with a variable pulse repetition rate. Using a combination of changes in the frequency and duration of the pulses will allow you to form a stable psychophysiological reaction to avoid the impact zone.

Using for exposure not one but several laser beams with different wavelengths will effectively resist the means of vision protection in the form of protective laser glasses.

The use of several laser beams instead of one will reduce the likelihood of damage to organs of vision by reducing the power of individual beams, compared with a single beam of high power with an increase in the total area of effective exposure.

The use of incoherent white light in addition to the laser radiation in the exposure zone will reduce the likelihood of irreversible loss of vision of the intruder due to the narrowing of the pupils in the dark.

In FIG. 1 shows a structural diagram of a device that implements the proposed method of non-lethal laser exposure to the intruder.

The device non-lethal laser exposure of the intruder contains a control unit 1, laser emitters with different wavelengths 2, a source of incoherent white light 3.

The device of non-lethal effects of laser exposure on the intruder works as follows: control unit 1 supplies a control signal to laser emitters 2 of different wavelengths and to an incoherent white light source 3. Laser emitters 2 generate pulses of variable duration and repetition rate. Incoherent light source 3 is in continuous operation. Radiation from sources 2 and 3 affects the intruder.
