Fig. 2.

Experimental comparison of phase recovered by the coherent Kalman filter as compared to the partially coherent Kalman filter, both with known and unknown sources. (Top) Measured source shape, with estimated source in white. (Second row) Phase recovered by the coherent Kalman filter is blurred for less coherent sources. (Third row) Phase recovered by the partially coherent Kalman filter (with known source). (Bottom) Phase recovered by the partially coherent Kalman filter with unknown source.
