[ Yuki, Gautam ]

We want to remotely control steeing PZT mirrors so its driver is needed. We already have a PZT driver board (D980323-C) and the output voltage is expected to be verified to be in the range 0-100 V DC for input voltages in the range -10 to 10 V DC.
Then I checked to make sure ir perform as we expected. The input signal was supplied using voltage calibrator and the output was monitored using a multimeter. 
But it didn't perform well. Some tuning of voltage bias seemed to be needed. I will calculate its transfer function by simulation and check the performance again tommorow. And I found one solder was off so it needs fixing.  

Reference:
diagram --> elog 8932
 

Plan of Action:

  • Check PZT driver performs as we expected
  • Also check cable, high voltage, PZT mirrors, anti-imaging board
  • Obtain calibration factor of PZT mirrors using QPD
  • Measure some status value before changing setup (such as tranmitted power of green laser)
  • Revise setup after a new lens arrives
  • Align the setup and check mode-matching
  • Measure status value again and confirm it improves
  • (write programming code of making alignment control automatically)
