-Stub page for now.  See subpages:
-== Discrete subsystem ==
+The ARSF LiDAR system, for data collected in 2009 onwards, is a Leica ALS50-II. This includes a full waveform upgrade for 2010 onwards. 
+
+The ALS50-II operates with laser radiation at 1064 nm. It works by firing a pulse every 4ns or 9ns and measuring the round trip time to when a reflection is detected. This is then converted into a distance. There are 2 banks of timing cards - each one with 4 cards. This means that it can measure up to 4 independent returns for each pulse (it only uses the 2nd bank of cards when operated at the higher pulse rate).
