An old elog that I forgot to post and was in my drafts.
The LC were scanned from 0-3..5V with 0.1V resolution
Measurements were taken at coating position of 0 and 28deg
All the measurement were saved with the the labview where we can even save std on each parameter.
Input_foldername=os.path.join(path, 'Polarization states/20240401')
input_filename= 'Mon, Apr 1, 2024 9-59-08 AM.txt'
for 0 deg
Output_foldername = os.path.join(path, 'Coating measurement/BB1-E03/20240401/0 deg')
output_filename ='Mon, Apr 1, 2024 3-52-42 PM.txt'
for 28 deg
Output_foldername = os.path.join(path, 'Coating measurement/BB1-E03/20240401/28 deg')
output_filename ='Mon, Apr 1, 2024 9-25-18 AM.txt'
The voltage of 0-3.5V was chosen in contrast to previous choice of 0-5V or 0-25V. It is because most of changes induced in azimuth and ellipticity due to LC is around this range of voltage.
