In this paper, we confirm the feasibility of circular SAR images using real SAR data in both modes: two-dimensional imaging for different view angles, or three dimensional imaging mode. This new imaging possibility demonstrates clearly the strong anisotropic behavior of the main scatterers at X-band. This proves both the limitations of the autofocus techniques base on tracking on isotropic stro...

We develop and experimentally test a method for three-dimensional imaging of hidden objects in a scattering medium. In our scheme, objects hidden between two biological tissues at different depths from the viewing system are recovered, and their three-dimensional locations are computed. Analogous to a fly's two eyes, two microlens arrays are used to observe the hidden objects from different per...

Mammalian development is a sophisticated program coordinated by a complex set of genetic and physiological factors. Alterations in anatomy or morphology provide intrinsic measures of progress in or deviations from this program. Emerging three-dimensional imaging methods now allow for more sophisticated morphological assessment than ever before, enabling comprehensive phenotyping, visualization ...

The principle of wavelength-scanning digital interference holography is applied to three-dimensional imaging of a small biological specimen. The images are reconstructed from a number of holograms digitally recorded while the wavelengths are varied at regular intervals, and the numerical interference of the multiple three-dimensional hologram fields results in tomographic images with narrow axi...

introduction: three-dimensional (3d) scanners are widely used in medicine. one of the applications of 3d scanners is the acquisition of anthropometric dimensions for ergonomics and the creation of an anthropometry data bank. the aim of this study was to evaluate the precision and accuracy of a modified 3d scanner fabricated in this study. methods: in this work, a 3d scan of the human body was o...
