Figures & Tables

Fig. 1. (a) Example of conventional TAI for a square array designed according to Eq. (1) with a fraction parameter of $β = 15$ , and (b) its reconstructed intensity distribution at the fractional distance. (c) Phase distribution within one period of the TAI and (d) its corresponding 3D multilevel steps structure.

Fig. 3. (a) Structure of the ( $m$ , $n$ ) cell in the BP-TAI and (b) its phase configuration. The rectangular opening has a width $Δ / 2$ and a height $h$ , and it is shifted from the center of the cell at ( $m Δ$ , $n Δ$ ) by $δ_{m n} Δ$ . (c) Phase distribution within one period of the BP-TAI with $β = 15$ . (d) Comparison diagram of the phase distributions along the line through the center of the BP-TAI and the conventional TAI with $β = 15$ .
