Laser US Navy creates plasma "UFO"

At the disposal of the naval forces (Navy) of the USA, the laser is able to create two - and three-dimensional plasma image that outsiders may take for unidentified flying objects (UFOs), writes Forbes, citing the relevant us patent.

According to the magazine, similar technology of the CPA is intended to deceive infrared missiles with homing warheads. In particular, the laser is placed in the tail of the plane, and the corresponding plasma target is created at virtually any distance from the aircraft.

In Popular Mechanics skeptical about this explanation of the nature of UFOs. The publication believe that only some of the disclosed incidents of unidentified flying objects, can be explained by the use of lasers. In particular, according to Popular Mechanics, these are the plasma image seen by the camera AN/ASQ-228 Advanced Targeting Forward-Looking Infrared (ATFLIR) of the F/A-18E/F Super Hornet.

The U.S. Navy patented technology to create images in the air to fool infrared and other sensors. This is based on years of laser-plasma studies and offers a completely new method of protection of aircraft against missiles, heat seeking. It may also give an idea about the source of some recent UFO sightings are military aircraft.

A sufficiently intense laser pulse can ionize the air, creating a flash of glowing plasma. Program "Laser effects plasma" plasma uses a single flash as stun grenades. A quick series of flashes can even be modulated for the transmission of the oral presentation (video here).

In 2011, Japanese company Burton Inc. has demonstrated the basic system, which created a moving three-dimensional images in the air with a series of rapidly generated plasma points (video here).

A more complex approach uses an intense, ultrashort, laser pulse samofokusirovka to create a glowing filament or channel of plasma (the effect discovered in the 1990-ies). Known as laser-induced plasma filaments (LIPF), they can be created at a distance from the laser at tens or hundreds of meters. Since LIPF conduct electricity, they have been investigated as a means of launching lightning or created lightning guns.

One of the interesting features of LIPF is that with proper tuning they can emit light of any wavelength: visible, infrared, ultraviolet, or even terahertz waves. This technology is the basis of the project of the Navy, which uses LIPF to create phantom images with infrared light, to deceive missiles, seek heat.

The Navy refused to discuss the project, but the work described in the patent of 2018:

"which laser source is mounted on the rear of the air vehicle, and in which a laser source configured to generate laser-induced plasma and laser-induced plasma acts as a lure for new threats to air means of transport".

Further, the patent explains that the laser creates a series of plasma columns in air, which form two-dimensional or three-dimensional image through a process of raster scan like a TV old model displays the picture.
