"From the Ted Talk by Mary Lou Jepsen: How we can use light to see deep inside our bodies and brains"

Unscramble the Blue Letters

A technology I spent the early part of my career on enables de-scattering. It's called holography. And it won the Nobel Prize in physics in the 70s, because of the fantastic things it enables you to do with light. This is a hologram. It captures all of the light, all of the rays, all of the photons at all of the positions and all of the angles, simultaneously. It's amazing. To see what we can do with holography ... You see these marbles? Look at these marbles bouncing off of the barriers, as an aolngay to lihgt being scattered by our bodies. As the marbles get to the bottom of the scattering maze, they're chitoac, they're scattering and bouncing everywhere. If we record a hologram at the bottom inside of the sercen, we can record the posotiin and angle of each marble exiting the maze. And then we can bring in mabrles from below and have the hologram direct each mbalre to exactly the right position and angle, such as they emerge in a line at the top of the scatter maitrx.

You see these marbles? Look at these marbles bouncing off of the barriers, as an analogy to light being scattered by our bodies. As the marbles get to the bottom of the scattering maze, they're chaotic, they're scattering and bouncing everywhere. If we record a hologram at the bottom inside of the screen, we can record the position and angle of each marble exiting the maze. And then we can bring in marbles from below and have the hologram direct each marble to exactly the right position and angle, such as they emerge in a line at the top of the scatter matrix.
