Mavic Air underside IR sensors

Hello guys and gals

When I turn on my MA, and look at the IR sensors on the underside. Only one appears to be flashing red? Any ideas anyone?

I'm pretty sure one sensor sends out the light, and the other receives the reflection.

Noticed that too on mine and assumed what @Jack Daw said.
