2.1 Overview
The VLS-128 sensor uses 128 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 assembly of laser/detector pairs spins rapidly within
its fixed housing to scan the surrounding environment, firing each laser over 18,500 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.
Sensor data is made available to your application via Ethernet in real-time in the form of UDP packets.
