A Light Detection and Ranging (LiDAR) system developed by researchers at the University of Texas at Austin and the University of Virginia can enhance weak signals reflected off faraway objects.

A new avalanche photodiode the researchers developed can amplify the photoelectric effect for light detection via a staircase-like alignment.

The researchers said its greater light sensitivity enabled it to generate a more comprehensive perspective for a car's onboard computers, while also removing noise.

The engineers intend to integrate the new device with an avalanche photodiode they invented last year to capture near-infrared light, for greater accuracy in fiber-optic communications and thermal imaging.
