FIG 2 (IMAGE) Compuscript Ltd Caption Experimental demonstrations of an all-optical 3D high-contrast object reconstruction system. (a) Schematic diagram of the all-optical high-contrast object 3D reconstruction. Different color planes represent different projection planes. (b) Contour information results of an observed object on different projection planes in Fig. (a). (c) The 3D model reconstructed by recombining the different projection results captured in Fig. (b). (d1)-(d3) The origin image, the 3D experimental reconstruction models of rotation interval angle is 16° and 4° of coriander seed, respectively. (e1)-(f3) 3D experimental reconstruction models of the mushroom model and lollipop model with the same type as Figs. (d1)-(d3). Credit OEA Usage Restrictions Credit must be given to the creator.
