A long-range electrochromic fiber for infrared camouflage and preparation method thereof are disclosed. The method includes: coating indium tin oxide dispersion, electrolyte solution, and electrochromic material on the surface of the metal fiber sequentially, and preparing counter electrodes and polymer protective layer on the outside of the electrochromic layer to obtain the long-range electrochromic fiber. The obtained long-range electrochromic fiber can realize the regulation of infrared emissivity, can be continuously prepared for more than 100 meters and has a good application prospect in infrared camouflage, wearable display, etc.

A pattern for camouflage and a method for making the pattern. The method includes taking photographic images from the perspective of the selected animal or bird. In one embodiment, the photographic image can be taken from above so as to create a finite background within the selected environment. In another embodiment, the pattern is adapted to be seamlessly repeatable across a surface. The method includes placing desired harvested abstracts into the photographic scene to obtain the overall desired effect of the camouflage pattern including color, composition, depth and repeat. The method also includes taking multiple photographs of the same scene from the same exact spot focusing on different parts of the photographic scene to add clarity to certain portions of the images, enhance depth, and reach desired color palate. The method includes adjusting the color of objects, including water within the photographic scene, to reflect true color of objects absent outside conditions.

Described herein are technologies related to passive or active cloaking devices. More particularly, the passive or active cloaking devices utilize input/output grating couplers and waveguides to create an impression of invisibility on an object that is covered by the passive or active cloaking devices.

A camouflage object including a body having an area and a camouflage pattern placed in the area. The camouflage pattern is formed by at least two first bands extending in the same first running direction across the area and having a first length, where the at least two first bands include a first perceptible characteristic and at least one second band extending in a second running direction across the area and having a second length, where the at least one second band includes a second perceptible characteristic. The at least one second band at least partially overlaps the at least two first bands. A plurality of zones is formed by the intersection of the at least two first bands and the at least one second band and have a pattern formed by the combination of the first perceptible characteristic and the second perceptible characteristic.

A device is provided for camouflaging an object from an infrared detection apparatus. The device includes a cloak positionable between the object and the infrared detection apparatus. The cloak includes a layer of infrared absorptive material including a plurality of silicon nanowires. A flexible substrate has a first surface operatively connected to an inner surface of the layer. The substrate includes a heat dissipation arrangement for dissipating heat generated by the cloak during operation. An array of infrared emitters is operatively connected to a second surface of the substrate. The array of infrared emitters selectively radiates an infrared pattern to disguise the object to the infrared detection apparatus.
