A high-resolution light detection and ranging (LiDAR) chip developed by researchers at the University of California, Berkeley (UC Berkeley) could pave the way for smaller, less-expensive LiDAR navigation systems.
The new LiDAR chip is based on a focal plane switch array, which can channel all available laser power through a single antenna at once.
The researchers also used microelectromechanical system (MEMS) switches that physically move the waveguides from one position to another; this allows 16,384 pixels to be placed on a 1-centimeter-square chip, with each pixel equivalent to 0.6 degrees of the array's 70-degree field of view.
A 360-degree view around a vehicle could be achieved by mounting several of these chips in a circular configuration.
Said UC Berkeley's Ming Wu, "There will be so many more potential applications once we shrink LiDAR to the size of a smartphone camera."
