We're going through transducers, active speakers, and microphones.

Imagine a choir of 9,000 singers and an audience of 9,000 people all listening carefully.

The transducers are controllable at a rate of 100 million times per second.

Together they fire in a pattern that sends out structured waves.

Those are the structured waves you're seeing.

The waves travel out at a speed of 1,481 meters per second.

We construct a ring of 40 of these systems, 70 centimeters in diameter.

The ring consists of 358,000 ultrasonic sensors.

The chips take turns sending out waves.

As the waves have a chance to dissipate, we fire the next one.

One by one, they fire at a rate of up to 1,000 times per second.

You're vibing out.

The waves travel across the tank in 480 microseconds, about 1 2,000th of a second.

Hundreds of thousands of transducers listen

Each sensor resolves motions smaller than the width of an atom, not micrometers or nanometers, but picometers.

Working together, hundreds of sensors can even push into the subatomic femtometer range.

Finer than the scale of atoms, a scale where we don't even have anything you've heard of.

The system captures data at a leisurely 17 gigabytes a second.

Gigabytes of sonic reverberations flow around your body.

And from vibrations, they form images with this device.
