It operates using infrared light. I don't know the exact physics behind it, but essentially, different temperatures show up differently on the infrared spectrum. It’s the same principle scientists used to map out object temperatures across the universe.

The temperature fluctuates by about 0.5 degrees throughout the day.

As for actually using the devices themselves, I don't have any hands-on experience.

Here’s a link to a book that breaks down the mechanics of sleep, plus some tips on how to get better rest in less time.
