Data is in the process of being uploaded - more will follow (last Update 6 March 2018)

timeresdata: A matlab data file with the raw and processed data for a ULH liquid crytsal cell. 
pubfig1: A matlab script for printing Fig. 1 and Fig. 2 in the publication

Simply load the data file and run the script to recreate Fig. 6 and Fig. 7.


List of key variables:
t: time (vector)
inputvoltage: Input voltage waveform (vector)
uphi: Demodulated phase vs time (vector)
deltam: Demodulated retardance vs time (vector)
meansig: Mean signal power vs time (vector)

setangle: The set of analyser angles (1:72 are for LCP, 74:145 are for RCP)
IntensityData: Photodetector voltage vs t [first dimension] and setangle [3rd dimension])
