The HALO Photonics Stream Line LiDAR system offers ultimate flexibility in deployment options, range setting adjustment, all-sky scanning, de-polarisation and real-time Doppler processing out to 12 km.

 

A HALO Photonics LiDAR system has operated continuously (24/7) at the Chilbolton Observatory since late 2006. It was originally set up to point vertically, but since the initial delivery, it has been upgraded with a dual polarisation measuring capability, a simple 1-axis tilting scanner and 100% duty-cycle data capture to 10 km.

Live data quicklooks and a complete data archive are available from the Radar group website.

The data below was collected using the UFAM HALO LiDAR located in Westminster, London – UK  during October 2007. The system was housed in a van, and was left unattended but controllable using remote access software.
