% Code 1: Fells et al. Dynamic phase measurement of fast liquid crystal phase modulators
% This zip folder contains: 
% 1) Matlab scripts to demodulate phase infromation from the interferometer
% 2) A set of raw data files captured from the measurement system
%
% To run the code, put the data files demodpm.m and procpm.m into the same folder, run Matlab, then execute:
% >> load pmdataXXXX.mat
% >> procpm
%
% The script calls demodpm.m to demodulate the phase
% The scrpt plots:
% 1) Input volatage of the signals applied to Pixel 1 and Pixel 2
% 2) The demodulated phase of Pixel 1 and Pixel 2
% 3) The phase difference between Pixel 1 and Pixel 2

% Each data file is relevant ro the figures in the manuscript as follows:
