  1. Phase Camera Review David Ottaway and Andri Grettarson

  2. PD Phase Camera 1/40 X Galvo Driver Monitor 40 X Control Room Computer 1/40 X Galvo Driver 40 X LVEA Computer ADC / DAC Sync.Signal RF Source Amp and LP Amp and LP

  3. Scan Pattern and Data Analysis Output Spiral Collect I/Q and Position Data Interpolate to Cartesian Coord. Display

  4. Sample Data Nominal Alignment Improved Alignment

  5. Control Screens

  6. Real Time Interpolated Results

  7. Control/Analysis/Display Control Room Data Handler Remote Data Handler / Camera Driver Underlying Labview Code

  8. Input Referred Readout Noise

  9. Comments Refresh rate: ~ 3 Hz without interpolation ~ 0.5 Hz with interpolation Electronics noise should be reduced, esp. line peaks. Should we write phasecamera data to frames? Requires five 2048Hz channels. Should be possible to get rid of LVEA PC and Labview and drive camera from AM modulated signal generator or VME style interface Camera has information not available elsewhere (spatial structure of the RF) => We should learn to use it!
