Sondrestrom Lidar Operation Log


Operator(s) : Christian Have Pedersen
Purpose : Near field trouble shooting.
Date(s) : 070210 - 070211
File(s) : L20070210_000 - L20070211_001
Comments : It is not possible to reduce near field noise using adjustable components in optical
as it is now. Experiments with shielding tubes is next. Furthermore the focus point
of the telescope should be verified.

L20070211_00001:53:53I am not able to remove near field noise just using the 1420cp
irises in the optical path. Futhermore, the frontend
might be off alignment, since return signal varies a lot and
randomly, when the iris is adjusted.
L20070211_00103:37:14Thats as good as it gets adjusting the optical path in0cp
the receiver.
