TED: Imaging at a trillion frames per second | Ramesh Raskar

The video introduces femto photography, a revolutionary imaging technique capable of capturing light in motion at one trillion frames per second. It explores the potential applications of this technology, such as seeing around corners and checking fruit ripeness. The video also discusses the creation of the femto camera at MIT and its future implications in fields like health imaging. The speaker calls for further research and innovation in this area.

What is one of the potential applications of femto photography mentioned in the introduction?

• Seeing around corners

• Measuring temperature

• Capturing images of stars

How does femto photography allow us to visualize light?

• By slowing down time by a factor of 10 billion

• By speeding up time by a factor of 10 billion

• By using ultraviolet light

• By using infrared light

What happens to the photons when they enter the bottle in the femto photography demonstration?

• They change color

• They scatter and create ripples

• They stop moving

• They disappear

Why does the tomato continue to glow after being hit by light in the femto photography demonstration?

• It is made of glass

• The light is absorbed completely

• The light bounces around inside the tomato
