Imaging Correlography Using Ptychography for Long-range Space Targets ImagingImaging correlography is an effective method for long-distance imaging, it recovers an object using only the knowledge of the Fourier modulus without the needs of phase information. A research team led by Prof. Dr. SONG Zongxi from Xi'an Institute of Optics...Mar 16, 2020 -
Scientists Build Novel Methods to Enhance the Accuracy of Remote Sensing Scene ClassificationDeep feature-based methods have received extensive attention and become the mainstream research in the remote sensing scene classification (RSSC) task. A new mothed, the end-to-end feature aggregation CNN (FACNN), is proposed to alleviate the problem that t...Mar 11, 2020 -
Scientists Successfully Grows Stacking Faults Free GaN on SapphireA research team led by Dr. WANG Jie from Xi'an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences (CAS) presents a unique growth technology to eliminate the stacking faults (SFs) in semipolar GaN grown on sapphire. Based ...Mar 10, 2020 -
Scientists Prevent Critical Collapse of Higher-order SolitonsSelf-trapped modes suffer critical collapse in two-dimensional cubic systems. To overcome such a collapse, linear periodic potentials or competing nonlinearities between self-focusing cubic and self-defocusing quintic nonlinear terms are often introduced. A...Mar 06, 2020 -
Scientists Solved Simultaneous Optical Trapping and Imaging In The Axial Plane For Light-matter InteractionOptical trapping has become a powerful tool in numerous fields such as biology, physics, and chemistry. But, in conventional optical trapping systems, trapping and imaging share the same objective lens, confining the region of observation to the focal plane...Mar 05, 2020
