WebLidar uses laser light to measure distances. A transmitter emits pulses of light, which reflect off surfaces and return to a receiver. The receiver records the time taken for each pulse of light to return, which is used to calculate the distance traveled by each beam. These times and distances yield a set of data points called a point cloud.
