Episode notes

Researchers have created a new way of seeing in the dark. They call it heat-assisted detection and ranging or HADAR. It uses physical information about objects as well as their heat signatures to allow a user to see in total darkness. As if it was daytime.

In this episode:

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.
