Detecting and Identifying Floor Vibrations through Interferometers
By Shashank Cheruvu
Interferometers are laser-based investigative tools that are highly sensitive to vibrations. Because of this, when placed on the floor, they can detect the small differences between the walking styles of different people, meaning that, if attached to a sufficiently trained neural network, we can discern the identity of a person who is walking without needing audio or video. This could be applied in the future as a surveillance tool, or more!
