[ros-users] unreliable height estimation with Hokuyo UTM-30LX laser due to smoothing?

I'm currently trying to use the Hokuyo UTM-30LX laser for height
estimation by redirecting some beams with small mirrors. The setup is
similar to the one used in
The problem I'm having is that it seems like the Hokuyo
smooths/filters the data and I can't get reliable measurements. It
works up to approx. 50cm, for higher distance the few redirected beams
seem to be smoothed out again.
Apparently the URG-04LX can be switched to a high sensitivity mode,
which supposedly mitigates such problems, but it seems this is not
possible on the UTM-30LX.

Has anyone use a Hokuyo UTM-30LX for something like this and
experienced the same problems?
Any ideas on how to improve it?

Cheers, Felix
