Episode notes

In your paper, you've developed something called a haydar system which seems to get around this problem. What really made me pursue these ideas is just simple things from science fiction to home discussions. And so one thing I've read about in terms of trying to understand like heat signatures to make night vision is a challenge that's called the ghosting effect. Can you explain what this is and why this is a challenge for you? So when you look at an image that is just generated by the heat signatures from the body, the entire environment around you is also emitting heat radiation. That actually bounces off your body and reaches the camera. But suppose your friend is taking a picture of you, you

00:46 How to see in the dark like it’s daytime

There are many methods for better night-vision, but often these rely on enhancing light, which may not be present, or using devices which can interfere with one another. One alternative solution is to use heat, but such infrared sensors struggle to distinguish between different objects. To overcome this, researchers have now combined such sensors with machine learning algorithms to make a system that grants day-like night-vision. They hope it will be useful in technologies such as self-driving cars.
