A look at (and inside) the Walabot “X-ray camera.” (not actual x-rays!)04:33

Vayyar have sent us a Walabot development unit to take a look at.
It’s based on the principle that if you compare the strength and time of an RF reflection between an array of antennas then you can create a complex 3D image of radio-reflective materials.
This implementation of the miniaturised RADAR technology has managed to fit an array of antennas in a small case the size of a smartphone, with the idea that it can be used to visualise through solid surfaces, giving your phone the ability to see through solid materials. One of the potential applications being for finding services buried behind walls.
It’s quite intriguing that they have created a dedicated chip that handles the RF transmission and detection for so many antennas.
Keep in mind that even though the unit “only” has 18 antennas, it can effectively triangulate between any group so that it’s resolution is effectively determined by the processing power of the unit that is converting the data to an image.
It’s important to note that this implementation of the technology is still very new, so it’s still being honed and developed. This video is just a quick glimpse at the potential for the unit. As time goes on and it finds suitable applications it has the potential for some very interesting products.
