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.
