HDL-64E S2 and S2.1 User’s Manual PrinciPLes of oPeration The sensor operates, instead of a single laser firing through a rotating mirror, with 64 lasers fixed mounted on upper and lower laser blocks, each housing 32 lasers. Both laser blocks rotate as a single unit. With this design each of the lasers fires tens of thousands of times per second, providing exponentially more data points/second and a more data-intensive point cloud than a rotating mirror design. The sensor delivers a 360° horizon

By using a network monitoring tool, such as Wireshark, you can capture and observe the packets as they are generated by the sensor. See Appendix E for the UDP packet format. The default source IP address for the sensor is 192.168.3.043, and the destination IP address is 192.168.3.255. To change these IP addresses,

The default is 600 RPM (10 Hz). Changing the spin rate does not change the data rate – the unit sends out the same number of packets (at a rate of ~1.3 million data points per second) regardless of its spin rate. The horizontal image resolution increases or decreases depending on rotation speed. See the Angular Resolution sec
