Problems solved by technology

However, this method of direct cooling to achieve infrared camouflage is not an ideal approach, because cooling will cause additional heat generation, which will be released from other places on the target, which may increase the target's chance of exposure

Embodiment Construction

[0029] The structural composition of the present invention is explained and illustrated below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, a vanadium dioxide-based active infrared camouflage structure of the present invention includes a heating substrate 1, a vanadium dioxide film 2 and an electrode pair 3;

[0031] The vanadium dioxide film 2 is coated or evaporated on the upper surface of the heating substrate, and the thickness of the vanadium dioxide film (2) is 10nm-1mm; the heating substrate 1 provides support for the vanadium dioxide film and changes the vanadium dioxide by electric current heating The temperature of the film 2; the electrode pair 3 is located at both ends of the heating substrate 1, connected to the external power supply and the heating substrate 1, and is used to change the temperature of the heating substrate, thereby adjusting the change of the vanadium dioxide emissivity.

[0032] Heating substrate 1 can choos...

Abstract

The invention discloses an active infrared camouflage structure based on vanadium dioxide, which comprises: a heating base, a vanadium dioxide film and an electrode pair; the vanadium dioxide film is coated or evaporated on the upper surface of the heating base; the heating base is vanadium dioxide While the film provides support, the temperature of the vanadium dioxide film is changed by current heating; the electrode pairs are located at both ends of the heating substrate, connected to the external power supply and the heating substrate, and used to change the temperature of the heating substrate, thereby adjusting the change of the vanadium dioxide emissivity. Infrared camouflage capable of low power consumption and fast adjustment.

Description

technical field [0001] The invention relates to an active infrared camouflage structure based on vanadium dioxide, which is especially suitable for the requirements of infrared camouflage or stealth on plane, curved and flexible surfaces. Background technique [0002] In nature, color-changing camouflage is a bizarre ability that many animals have evolved as an adaptation for survival. For example, chameleons and octopuses can actively change the color of their skin according to their surroundings to achieve camouflage or invisibility. Similar to the camouflage of animals in the visible light band, camouflage in the infrared band is also an extremely important technology, and has broad application prospects in both military and commercial aspects. [0003] Infrared thermal imager is the most important device to realize infrared detection and reconnaissance. It displays the measured target by measuring the thermal radiation energy of the object. According to the law of ther...
