Can Metallic Metasurfaces Used for Terahertz Nanofilm Sensing?For ultrasensitive sensors, the high Q resonance with extremely narrow bandwidth is important and necessary, which indicates the lower rate of energy losses and supports strong interaction between electromagnetic waves and analytes.
However, the metalli...Jun 16, 2020 -
Deep learning networks find a new application on phase-contrast imagingPhase-contrast imaging has been widely applied in optical and X-ray measurements since the phase contains information about the 3D morphology and refractive index of the specimen. A phase map can be retrieved from a single-distance coherent diffraction imag...Jun 10, 2020 -
New Multispectral Curved Compound Eye Camera with Ultra Large Field View is AchievedMultispectral imaging technology has found wide applications in remote sensing for it has a relatively high spectral resolution.
But the existing technologies have many shortcomings such as low system integration, high complexity, small field of view (F...Jun 09, 2020 -
Scientists Realize High Power High Repetition Rate Laser Output Based on Single Crystal FiberHigh repetition rate, high energy ultra-fast laser is indispensable in industrial application and scientific research. The most common way to obtain high power ultra-fast laser is through laser amplification.
However, the small cross section of fiber am...Jun 02, 2020 -
Scientists Propose A High Contrast and High-resolution Ghost Imaging in Microscopic RegimeGhost imaging is a technique nonlocally produces an image of an object. The output of a (partially) coherent light source of the technique is split into two: one beam hits the unknown object while another severs as a reference and respectively record the ph...May 21, 2020
