The Hokuyo UTM-30LX-EW scanning laser rangefinder is a small, accurate, high-speed device for outdoor robotic applications. 

uses Ethernet interface for communication

can obtain measurement data in a wider field of view up to a distance of 30 meters with millimeter resolution. 

This device uses multi-echo technology for detection. 

allows for receiving multiple reflected waves per transmitted laser pulse in order to obtain usable measurement data.
