| 2 | Use of focus stacking and SfM techniques in the process of registration of a small object hologram显示文摘In this Letter,a method for shape visualization of small objects(microscopic)in the form of a hologram is presented.It consists of a standard optical set-up for small object registration(i.e.,stereoscopic or biological microscope).The focus stacking technique is used to obtain a series of images with increased depth of field and on them a shape reconstruction procedure(structure from motion,SfM)is made.With use of a dense cloud of points,a sequence of parallax-related images suitable for Geola’s digital holographic printing is generated.The holographic printer produces single-parallax holographic(full three-dimensional)images of real or virtual objects. | Sławomir Pasko Marek Sutkowski Ramunas Bakanas | 2020 | Chinese Optics Letters2020，18，6： | 0 |
