2.1 Overview
The VLP-16 sensor uses an array of 16 infra-red (IR) lasers paired with IR detectors to measure distances to objects. The
device is mounted securely within a compact, weather-resistant housing. The array of laser/detector pairs spins rapidly
within its fixed housing to scan the surrounding environment, firing each laser approximately 18,000 times per second,
providing, in real-time, a rich set of 3D point data.
Advanced digital signal processing and waveform analysis provide highly accurate long-range sensing, as well as cal-
ibrated reflectivity data, enabling easy detection of retro-reflectors like street-signs, license plates, and lane markings.
Combining 16 laser/detector pairs into one VLP-16 sensor and pulsing each at 18.08 kHz enables measurements of up to
300,000 data points per second -- or double that in dual return mode.
