Researchers developed a new smartphone-based digital holographic microscope that enables precision 3D measurements ... step Fresnel diffraction to calculate the diffraction patterns.

If you then move the sample slightly, the diffraction pattern shifts ... So the researcher puts a drop of their own blood on the surface of the CCD and covers it with a bit of polyvinyl film ...

that the obtained diffraction pattern is guaranteed to be uniquely sensitive to the surface structure. "Helium atom scattering is a well-established technique that uses the position and intensity ...

China presented a new label-free 3D microscopy technique, termed transport of intensity diffraction tomography with non-interferometric synthetic aperture (TIDT-NSA). A unified theoretical ...

Engineers at the UCLA Samueli School of Engineering have introduced a universal framework for point spread function (PSF) ...

But because they are so short, the diffraction pattern can be recorded before a sample blows apart. Recent advances in XFEL technology have allowed a more than 10 20-fold increase in the intensity of ...
