3mm Photodiode Characterization for Enhanced LIGO
Entry  Fri Jun 29 11:26:04 2012, Zach, Optics, Characterization, RoC measurement setup RoC_measurement_setup.pngRoC_measurement_setup.graffle.zip
Here is the proposed RoC measurement setup. Koji tells me that this is referred to as "Anderson's method".
We would like to use a linear cavity to measure the RoC of the curved mirrors independently (before forming the ring cavity), since the degeneracy
of HOMs will make the fitting easier.

Here is a more detailed version of the setup, so that we can gather the parts we will need.

Nic Smith sent me a bunch of elog lists where the results of the mode scan can be found.
From Nic:
There have been many mode scan analyses done at LLO:
