Figure 1
(a) Sketch of the SAInIm recording approach: p is the distance between EIs, \(I_{k,l}\) is the \(k,l-\)EI and z is the pick-up distance. \(N_H\) and \(N_V\) are the number of acquired EIs in horizontal and vertical directions, respectively. (b) Scheme of a 3 \(\times \) 3 EIs set. (c) Sum of the EIs, which represents the zero refocusing. (d) The refocusing procedure to three different planes of \(z_1\), \(z_2\) and \(z_3\). The lower row shows the associated changes during the focusing for each pixel (see Fig. 172).
