  • Density measurements of laser interaction with ordered structure... ... mean electron density of the pre-plasma created by a pre-pulse with different time delays. This research will allow a better understanding of the generation of fast protons from the interaction between a structured pre-plasma and a high intensity laser.
  • 3D dif fractive lenses to overcome the 3D Abbe subwavelength dif... ... optics the curvilinear 3D diffractive conical optics is capable of overcoming 3D Abbe barrier with a focal distance F greater than 2. The focal intensity distribution for such type of lenses is not circularly symmetric and thus the focal spot in the
  • Control and image processing for streak tube imaging lidar based... ... while the image processing is finished by MATLAB. A STIL imaging experiment is carried out in the laboratory. We obtained the intensity and range images of targets with pseudo color by image processing and reconstruction for a set of raw streak images of ...
  • Suspended twin-core fiber for optical switching ... fiber, the pressure-induced refractive index change of the two fiber cores will contribute to the periodical change of the intensity of guided light in the fiber core. The mode coupling of two cores under different hydrostatic pressure and influences of ...
  • Tunable rectangular array illuminator in periodically poled LiNb... ... The illuminator is formed based on the Talbot self-imaging effect by applying an electric field on PPLN. The intensity distribution of rectangular array could be precisely modulated. Compared with other array illuminators, this tunable illuminator uses a ...
  • Effects of charge compensation on red emission in CaYAl3O7:Eu3+ ... ... . In addition, the influence of charge compensation ion Li+ which has a more obvious role in improving luminescence intensity on CaYAl3O7: Eu3+ phosphor is intentionally discussed in detail and a possible mechanism of charge compensation is given. The ...
  • High-throughput deconvolution-resolved computational spectromete... ... a dual-path optics to measure both non-dispersed and dispersed light intensity which comes from the wide-slit. While the dispersed light intensity is result of the non-dispersed light convoluted spectrum of the source, the spectrum can be
  • Speckle noise reduction in digital holography with spatial light... ... modulator is adopted to introduce random phases to the illuminating beam. Multiple holograms are reconstructed and superimposed, and the intensity is averaged to smooth the noise. The adaptive algorithm based on the nonlocal means is designed to further ...
  • Study on diffraction characteristics of a planar diamond wavegui... A numerical simulation is performed to study the far-field diffraction properties of planar diamond waveguides. The far-field intensity distributions of a planar air waveguide and a diamond waveguide with different distances are given by numerical ...
  • Propagation and interaction of two-component vector dark soliton... ... interaction are analyzed. The nonlocality degree determines the intensity distribution of the dark solitons in the stationary states, enhances the intensity transfer between two vector solitons, and affects the propagation and interaction. The numerical ...
