Calibration Start Linear stages positionning Start acquisition Trigger scanner mouvement movement completed ? No Yes Data download from picoscops Data integrity checks Data processing and data reduction System initialisation Data recording to file All position performed No Yes Report generation End of program Next position

BWS Calibration Bench Design Laboratory test bench  LTS150  Pico 5444B

BWS Calibration Bench Design  Move to Home position  Move to Absolute position  Jog  Read from Picoscope  Create waveform / pulse on the Picoscope  Change Picoscope settings  Change Thorlabs settings  Read/Write Initialization settings  Make cycle: Jog – Pulse – Acquire signal – Jog (…) Done: Linear stages positionning Start acquisition Trigger scanner mouvement Data download from picoscops System initialisation Data recording to file All position performed

BWS Calibration Bench Design

Scans: Jog – Pulse – Acquire Signal - Jog dSpace ↓ WS movement

BWS Calibration Bench Design  Integrate the dSpace system to trigger scanner movement  Decide the correct parameters for the Thorlabs and Picoscope. According with the new BWS bench  Perform data processing and data reduction  Perform data integrity check  Create a nice GUI  Integrate all channels from picoscope  Record picoscope channels into file To do:
