3D Imaging Through Walls

O.K. it’s not lidar, but those incredible scientists at the MIT Media Lab have been at it again. This time it’s a time-of-flight microwave camera that can see through solid objects, like walls – incredible!

Here’s some of what makes this big news:

Visible light has a wavelength between 390nm and 700nm, while our camera sees between 2.5cm and 4cm (much larger). While classical radar-imaging devices can perform these tasks, they do so with highly complex systems which are out of the reach of the consumer. We introduce a radar imaging architecture which makes imaging at these long wavelengths more accessible, while enabling all of the following:

  • higher resolution imaging
  • all of the electronics constrained to a small 10” x 10” space
  • Fewer detectors necessary
  • Better detection of specular (mirror-like) surfaces
  • Multi-spectral imaging
  • Time-resolved imaging (capturing Microwaves in flight)

The aim of our work is not just to detect objects, but also to form images in 3D. Bring it on.

Thanks to loyal supporter Brent Gelhar for the lead.

    Hello,If the wall is covered with sheets of aluminum,are capable of detecting their targets?
