Research on frequency modulation character of the current driven DFB semiconductor laserThis paper presents a study on the issue of current-driven distributed feedback (DFB) semiconductor lasers (LD) experiencing nonlinear laser frequency variation in the course of linear frequency modulation. Cunxiao Gao’s research team establish a theoretic...Nov 27, 2019 -
Star Identification Algorithm Based on Oriented Singular Value Feature and Reliability Evaluation MethodDesheng wen’s research team present a full-sky autonomous star identification algorithm aimed at solving the "lost-in-space" problem in this paper. It mainly consists of two steps: an initial match step and a reliability evaluation step. Oriented singular ...Nov 27, 2019 -
Noise-resistant matching algorithm integrating regional information for low-light stereo visionLow-light stereo vision is a challenging problem because images captured in dark environment usually suffer from strong random noises. Some widely adopted algorithms, such as semiglobal matching, mainly depend on pixel-level information. The accuracy of loc...Nov 27, 2019 -
Tunable broadband emission from red to blue by gamma radiation in multicomponent phosphate glassesPengfei Wang’s research team demonstrate for the first time that the tunable broadband emission from red to blue can be obtained by gamma radiation in multicomponent phosphate glasses. Gamma radiation causes the increased phosphate-related non-bridging oxy...Nov 27, 2019 -
Adaptive-window angular spectrum algorithm for near-field ptychographyNear-field ptychography provides advantages over far-field ptychography that large field-of-view (FOV) can be imaged with fewer diffraction images, and with weaker requirements on the detector dynamic range and beam coherence, which has drawn attention rece...Nov 22, 2019
