Building a tower at AO9



    We've tried using a laser scanner from AO9 to measure the dish. There was talk of building a tower around ao9 so the laser scanner beam would make a smaller angle between it and the surface normal. This should help on the returned signal. The amount will depend on how diffuse the scattering off the dish is.

    The setup would look like:

angle setup

I've plotted the measurements for various heights above the center of the dish, (.ps) (.pdf)

The current height of ao9 is probably 1.5 to 2 meters.
