    Enhancement of low-quality reconstructed digital hologram images based on frequency extrapolation of large objects under the diffraction limit

    During the reconstruction of a digital hologram, the reconstructed image is usually degraded by speckle noise, which makes it hard to observe the original object pattern. In this paper, a new reconstructed ima...

    Effects of carrier screening and state filling on the carrier scattering of Si doped GaAs

    Femtosecond spectroscopy studies on highly Si-doped GaAs show that the excited carrier initial scattering is reduced by the enhanced carrier screening and state filling.
