Will technology finally trump camouflage?

Some years ago I wrote a Weekend Wings article about stealth and camouflage technology, and how it’s evolved over the years.  A recent article in Gizmodo covered the field of personal camouflage technology, and gave several examples of the latest developments in the field.

However, I’ve been following with great interest the development of hyperspectral imaging and its application to military reconnaissance and sensors.  It’s almost ready to hit prime time, although the initial sensors using it will be big, very expensive, and a bit too sensitive for most battlefield conditions.  (We’ve discussed one of them in these pages before.)  I’d give it a few years at most before they develop into something small and portable enough to be mounted on most combat vehicles, and incorporated into night-vision goggles and weapon sights.

Hyperspectral imaging uses spectroscopy technology to identify the actual materials it sees, not just what they look like.  An artificial intelligence computer system could scan a hillside using such a sensor and decide, “That looks like rock, and according to its spectral radiation, it’s granite; . . . that looks like a tree, and according to its spectral radiation, it’s wood; . . . that looks like a bush, but according to its spectral radiation, it’s cloth.  Shoot it!”

This technology would mean that visual or infra-red spectrum camouflage would become largely irrelevant on a high-technology battlefield (although, of course, it would remain very useful when not confronted with such sensors).  We’ve already seen that smartphones and even eyeglasses can be converted into night vision devices.  How long will it be before hyperspectral imaging technology devolves to common electronic appliances in the same way?



  1. Funny but I recall reading that during WWII color blind individuals were used to spot camouflaged materials or sites.

  2. It's an arms race. Camouflage is losing at the moment, but as these sensors become more available, I predict that camouflage will be adapted to fool them.

  3. As my "Minecraft" playing kid would say, "Bedrock armor."
    If it's totally passive, then it will be interesting to watch developments. If it's active, depending on the reflected light from a beam on the system, then it's making the user a target.
