    (a) Schematic of CI. (b) Result reconstructed from the entire 3600 measurements. L represents lens.
    Distribution of the |y| and the threshold T1.
    Results obtained with different thresholds. (a) Image reconstructed from 1757 measurements selected by yT1, and (b) image reconstructed from the remaining 1843 measurements. (c) Image reconstructed from 1742 measurements selected by yT2, and (d) image reconstructed from remaining 1858 measurements. (e) Image reconstructed from 954 measurements selected by yT, and (f) image reconstructed from remaining 2646 measurements.
