Velodyne HDL- 64e High definition Lidar: https://www.youtube.com/watch?v=EYbhNSUnIdU

This sensor is able provide ample information about the surrounding environment of the laser. The sensor is able to synchronize its data with time pulses. The sensor can be used for vehicle navigation, three dimensional mapping, surveying, and industrial automation. Unlike the SICK laser this sensor is able to get a 360o field of view with a frame rate of 5 Hz to 15 Hz, which gives about 1.3 million points per second to the output. Velodyne provides a pre-programmed GPS receiver.

How does the output look?

The sensor output is sent in UDP Ethernet Packets. Each packet contains a header, data payload of firing data and status data.
