Jones matrix components extraction

if i have interferogram then how to extract Jones matrix phase and amplitude components. I am unable to extract all 4 phase and 4 amplitude components. Here interferogram is also generted by matlab not by experiment , so please suggest me where is my mistake that's why not getting results.

Hi Neha

Extracting all four phase and amplitude components of a Jones matrix from interferograms requires multiple measurements with different input and output polarization states. Kindly refer to the following steps to generate and analyze data correctly.

1. Define polarization states by using common polarization vectors like Horizontal (H), Vertical (V), +45° (P), and -45° (M)

H = [1; 0];
V = [0; 1];
P = [1; 1]/sqrt(2);
M = [1; -1]/sqrt(2);

2. Multiply your Jones matrix by each input vector.

E_H = J * H;
E_V = J * V;
% ... and so on

3. Generate intensities by projecting outputs onto analyzer states:

I_HH = abs(H' * E_H)^2;
%Repeat for other input-analyzer pairs to build a dataset.

4. Set up a system of equations using these intensities to solve for the Jones matrix elements.

I hope this helps.
