I optimized I/Q demodulation phase for each QPD segments. Here are the optimal demodulation phases. Note that the optimal demodulation phases are keep changing during this measurement.
I optimized I/Q demodulation phase for each QPD segments. Here are the optimal demodulation phases. Note that the optimal demodulation phases are keep changing during this measurement. DDS phase should be around 150 deg.
