The experimental results of DDIPHM with BEMD. (a) The phase image of microstep measured by DDIPHM with BEMD. (b) The surface profile of the microstep measured by DDIPHM with BEMD. (c) The height profile lines plotted along the black line in Figure 4(b) measured through stylus profilometry, DDIPHM, DDIPHM with BEMD, and DDHM (angular spectrum method, reconstruction distance  mm). The black rectangular shows the magnified part.
