    Abstract: PROBLEM TO BE SOLVED: To provide a self-calibration procedure for polarimeter, eliminating the need for input signals to be used as known.SOLUTION: Self-calibration data is taken by moving a polarization controller between several random and unknown states of polarization (SOPs) and recording the detector output values (D, ..., D) for each state of polarization. These values are then used to create an "approximate" calibration matrix. In one exemplary embodiment, the SOP of the incoming signal is adjusted three times (by adjusting a separate polarization controller element, for example), to create a set of four detector output values for each of the four polarization states of the incoming signal - an initial calibration matrix. The first row of this initial calibration matrix is then adjusted to fit the power measurements using a least squares fit. In the third and final step, the remaining elements of the calibration matrix are adjusted to satisfy a given constraint (for example, DOP=100% for all SOPs).
