RU68114U1 - ADAPTIVE MASK FILM - Google Patents

Abstract

The invention relates to camouflage, and in particular to camouflage coatings having a deforming visual and thermal color, and can be used in the industrial production of standardized panels for the formation of field coatings of various sizes and shapes for equipment and military objects, as well as camouflage suits for camouflage personnel. The inventive adaptive camouflage film containing many geometrically formed hollow cells of optically transparent elastic material placed on a common surface, allows, according to a given program, to change the visual (infrared and other) contrast of the masked object on the ground. The contrast of the terrain and the target is fixed in a certain time sequence using the remote lens of a digital multispectral camera and is processed by a computer that generates the appropriate control commands for mini-compressors. The program implements a change in color and surface temperature of the film (masked object) - depending on the pressure (on temperature) of the air supplied to the cell. Mini-compressors controllably supply air to the film cells under pressure, causing a change in wall thickness, which leads to a change in the color of the interference color of the hollow cells. The use of heated (cooled) air in various parts of the camouflage film also changes the thermal picture of direction finding of the masked object - the visual (infrared, etc.) contrast of the masked object on the ground. Changing the size of the cells leads to a change in surface roughness.

Description

The invention relates to camouflage, and in particular to camouflage coatings having a deforming visual and thermal color, and can be used in the industrial production of standardized panels for the formation of field coatings of various sizes and shapes for equipment and military objects, as well as camouflage suits for camouflage personnel.

Currently, camouflage clothing is used to hide personnel from visual observation, photographing, and other methods of optical reconnaissance: camouflage overalls and suits.

Concealment of military equipment, vehicles and fortifications from optical reconnaissance equipment is carried out using time sheet fabric camouflage sets MKT and the universal frameless mask “Tent”.

To counter enemy radar reconnaissance, angular reflectors of the OMU and Pyramid type are used to create radar jamming masks, to simulate and hide bridges and equipment both on land and on water.

To mislead the enemy, regarding the location and composition of their forces and means, technology models are used.

The above methods and means of camouflage are ineffective in modern dynamic combat, due to a number of drawbacks, the main of which are: large mass (40-250 kg), deployment time (5-20 minutes), static with a constant change in the combat situation.

The inventive adaptive camouflage film containing many geometrically formed hollow cells of optically transparent elastic material placed on a common surface, allows, according to a given program, to change the visual (infrared and other) contrast of the masked object on the ground. The contrast of the terrain and the target is fixed in a certain time sequence using the remote lens of a digital multispectral camera and is processed by a computer that generates the appropriate control commands for mini-compressors. The program implements a change in color and surface temperature of the film (masked object) - depending on the pressure (on temperature) of the air supplied to the cell.

Mini-compressors controllably supply air to the film cells under pressure, causing a change in wall thickness, which leads to a change in the color of the interference color of the hollow cells. The use of heated (cooled) air in various parts of the camouflage film also changes the thermal picture of direction finding

masked object - visual (infrared, etc.) contrast of the masked object on the ground. Changing the size of the cells leads to a change in surface roughness.

In general, the ongoing changes cause distortions of the standard (“portrait”) of the masked object. All this will lead to the admission of the object by the enemy during reconnaissance.

The implementation of the invention allows using a multifunctional adaptive camouflage film to automate the process of controlling the camouflage (reducing the visual and other contrast of the masked object) in accordance with the contrast of the terrain, lighting conditions, etc.

When observed from the enemy side, the cavity of the camouflage film is:

the first surface is a convex mirror;

the second surface is a flat mirror.

The presence of these surfaces causes the occurrence of effects:

dual display;

changes in the polarization of the reflected radiation;

changes in the color of the bubble with a change in the film thickness due to the phenomenon of interference on thin surfaces (Newton's colors).

The color of the film cavity occurs due to the fact that the film cavity has a different thickness and the refracted rays do not fall into focus. In this case, there are always rays that have passed the path of different optical magnitudes, and interference will occur (figure 2).

When the film cavity is illuminated in white, the interference pattern acquires a multicolor color. Interference in this light can be observed only on very thin films.

In monochromatic light, which is characteristic of laser radiation, an interference pattern can also be observed on thick films.

On the wedge-shaped part of the film cavity, the interference pattern is stripes of equal thickness parallel to the edge of the cavity of this part of the film. The interference pattern is observed only from a narrow (wedge-shaped) part of the film cavity, for which

where i is the angle of incidence of the beam;

ψ is the angle at which the radiation source from a given point is visible;

h is the thickness of the film cavity at the observation point;

λ is the radiation wavelength.

When changing the viewing angles from the perpendicular to the surface of the cavity, blue appears, then green, yellow, orange and red.

At relatively large viewing angles, the rays are completely reflected by the back surface of the bubble and it seems silvery.

Claims (1)

An adaptive camouflage film containing a multitude of geometrically formed hollow cells made of optically transparent elastic material placed on a common surface, characterized in that to change the color of the interference coloring of the hollow cells, a change in the thickness of the cell walls is used due to the controlled air supply under pressure, while using heated ( cooled) air in various parts of the camouflage film changes the thermal picture of direction finding of the masked object.
