3D imaging by two-color Ewald spheres with optical lasers

【摘要】 3D imaging techniques such as computed tomography,ultrasonography,and magnetic resonance imaging usually combine many scans computationally.Here,we report a 3D imaging approach using an optical-laser diffraction microscope with two different wavelength lasers in the same orientation.A double-layered sample constructed of silica spheres is used for coherent diffraction imaging;with two lasers at 543 and 432 nm.The diffraction patterns obtained using a planar detector at a high numerical a pert are arc projected onto the Ewald spheres.3D images of the double-layered sample are successfully reconstructed from the two-color spherical diffraction patterns.更多还原
