Simultaneous reconstruction of δα and for one point absorber and one point scatterer, both located at the depth (all lengths in centimeters). The absorber is located in the lower left corner the scatterer is located in the upper right corner Other parameters are the same as in Fig. 4. The images for δα are not calibrated, since reconstructed δα has no maxima in the z direction; calibration of images is done as in Fig. 4.
