Calibration

I'm working on a simple model of the differential arm length sensing and control loop to guide work on real-time calibration. The model is based on Figure 6-1 in Rana's thesis. We will start tests for a real-time calibration system on one of the 40 m arm cavities using the digital control system. - Eric Hendries

= Calibration Using Green = Calibration/SoCal

OSEMs

The rough calibration of the OSEMs we have now (2009 - the Adhikari/Fritschel OSEMs from 1999) is 2V/mm.
Then the signal gets whitened in hardware with a 30,100:3 (poles:zeros) whitening filter with a gain of 1 at DC.
The ADC calibration is then 16384 cts/V.
