“…Then, a possible improvement for further accelerating acquisition would be to use advanced reconstruction methods, which require much less data for precise specimen reconstructions than direct Fourier transform [86][87][88][89][90]. The reconstruction speed may be lower, as in particular iterative methods are slower, but acquisition could be simplified and accelerated, and such approaches could also benefit from much faster GPU reconstructions.…”

“…The reconstruction speed may be lower, as in particular iterative methods are slower, but acquisition could be simplified and accelerated, and such approaches could also benefit from much faster GPU reconstructions. Published work on TDM [17][18][19]27,[41][42][43][44]53,54,[86][87][88][89][90][91] have clearly demonstrated the usefulness of accessing the index of refraction distribution at microscopic scale, for biological research as well as work on artificial samples. But note that absorption is often not discussed, while it has been shown that refraction and absorption indeed provides complementary information [25,26,32,37,38,[45][46][47].…”

“…For the particles with a radius comparable to the wavelength of the laser, the modulation of the light field is mainly manifested by Mie scattering, whereas for particles with radii much larger than the wavelength, the modulation mainly follows Fraunhofer diffraction, which is the approximate solution of Mie scattering in the macroscopic field [34,35].…”

Laser-induced bulk impurity damage has always been a difficult issue in optical systems, affecting the signal-to-noise ratio, beam quality, and other vital laser parameters. In this study, the generation mechanism of bulk damage morphology is demonstrated through a combination of experiment and theory. The growth mechanism is then represented through parameter control. Finally, a general conclusion of bulk damage generation is obtained alongside a reasonable control range of dangerous parameters. The damage area is described comprehensively, and the guiding conclusions of dangerous parameters are given, providing theoretical support for precision optics processing, high-power laser design and other projects.

“…The structure of natural particles can be inferred through the VSF, while a 3D VSF should be measured if the suspensions are not ideally spherical or isotropic. In Ding's work, an algorithm utilizing a 3D VSF to retrieve the size parameters of an ellipsoid and other nonspherical particles was proposed [21].…”

The measurement of the volume scattering function (VSF) of suspended particles is an ongoing research topic since it has the potential to provide a rapid, nondestructive means of analyzing hydrosols. Despite the success of scattering theory, the measurement of multidirectional scattering intensity distributions over a wide, continuous range of scattering angles and multiple scattering planes, which is described by a three-dimensional VSF (3D VSF), has proven to be difficult. To measure the 3D VSF of submicron particles suspended in water, a measurement approach is proposed, built and tested with several standard submicron particles with diameters ranging from 60 nm to 1 μm. The experimental results indicate that the proposed setup can obtain an accurate 3D VSF for scattering angles from 21°to 160°and azimuthal angles from 1°to 179°. Comparisons between the experiment and theory show a high level of consistency for particles with diameters less than 200 nm. The variation in the VSF in response to the polarization direction of the incident light is also discussed. Both the experiment and theory show the potential of the device to detect the 3D VSF of marine submicron biological particles.
