Laser light is focussed at the particle cloud and the light is scattered at an angle that is dependent on the size of the particles; smaller particles scatter the light at bigger angles than do larger particles. Generally, assumptions are made that the particles are spherical and that the ...
4. What are some real-life examples of diffraction? Diffraction can be observed in various natural and man-made situations. Some examples include the colorful patterns formed by light passing through a CD or DVD, the rainbow-like patterns created by oil on water, and the sound of a voice ...
Novel X-ray methods are transforming the study of the functional dynamics of biomolecules. Key to this revolution is detection of often subtle conformational changes from diffraction data. Diffraction data contain patterns of bright spots known as reflec
Based on the transformation acoustics methodology, the design principle for achieving an arbitrary shape magnifying lens (ASML) is proposed. Contrary to the previous works, the presented ASML is competent of realizing far-field high resolution images and breaking the diffraction limit, regardless of th...
With further optimization of the automated image analysis code and parallel execution on multiple GPUs, we expect that, in the near future, real-time diffraction image processing for cell classification can be scaled up to a rate of 103images per second. Figure 3 shows some examples of recent ...
Experimental implementation and image reconstruction of SR-FACT To increase the temporal resolution while measuring the scattered optical field of light passing through biological samples due to the inhomogeneous distribution of the RI, we built an off-axis holographic ODT system based on a commercial ...
Image plate CCD detectors were used to collect pressure dependent X-ray diffraction data at the Advanced Light Source Beamline 12.2.2. An X-ray wavelength of λ = 0.4959Å was selected using a Si(111) double-crystal monochromator. Exposures time varied between 10 and 30 secs. ...
of light and will have substantially different blinking properties which can make them less likely to be detected. Conversely, if the background is close to focus, then the much higher labelling density in the sample structure may cause a higher proportion of background fluorophore to be detected...
Here we extend the super-oscillation concept into the vectorial-field regime to work with circularly polarized light and experimentally demonstrate, for the first time, a circularly polarized optical needle with sub-diffraction transverse spot size (0.45λ) and axial long depth of focus (DOF) of ...
