Real-time optical manipulation of particles through turbid mediaComplex diffusive scattering media pose significant challenges for light focusing as well as optical imaging to be implemented in practice. Recently, it has been demonstrated that the wavefront shaping technique can be applied to realize focusing and imagin...Nov 27, 2019 -
Three-dimensional space optimization for near-field ptychographyA multiple slices approach in ptychography, termed 3ePIE algorithm, solves the multiple scattering problems of thick samples, which is crucial to biomedical imaging and in situ studies. However, it is unclear how many slices need to be separated and what th...Nov 27, 2019 -
The Spectral-Spatial Joint Learning for Change Detection in Multispectral ImageryChange detection is one of the most important applications in the remote sensing domain. More and more attention is focused on deep neural network based change detection methods. However, many deep neural networks based methods did not take both the spectra...Nov 27, 2019 -
Indium selenide as a saturable absorber for a wavelength-switchable vector-soliton fiber laserChao Zeng’s research team experimentally demonstrate that indium selenide (In2Se3), a III-VI group layered chalcogenide compound. can be used as a saturable absorber (SA) for a wavelength-switchable vector-soliton fiber laser. The modulation depth of the I...Nov 27, 2019 -
Generation of coexisting high-energy pulses in a mode-locked all-fiber laser with a nonlinear multimodal interference techniqueWei Zhao’s research team demonstrate a passively mode-locked all-fiber laser incorporating a piece of graded-index multimode fiber as a mode-locking modulator based on a nonlinear multimodal interference technique, which generates two types of coexisting h...Nov 27, 2019
