Mayan Artifacts Found in Jungle
Shine a small light at a surface and measure the time it takes to return to its source. … The LiDAR instrument fires rapid pulses of laser light at a surface, some at up to 150,000 pulses per second. A sensor on the instrument measures the amount of time it takes for each pulse to bounce back. This is the technique that’s been used to locate 61,480 lost Mayan structures in the jungles of Guatemala — an expanse large enough to sustain a population approaching 11 million people.
