Large-scale phase retrieval

Wide field of view and high resolution are both desirable for imaging applications, providing multi-dimensional and multi-scale target information. As the recent development of phase imaging, large-scale detection has been ...

Three new ultra-faint dwarf galaxies discovered

Using the Hubble Space Telescope (HST), astronomers have detected three new ultra-faint dwarf galaxies associated with the nearby spiral galaxy NGC 253. The newly found dwarfs turn out to be among the faintest systems so ...

Phosphorescent material inspired by 'glow in the dark' wood

Scientists have harnessed the natural ability of wood to faintly glow to develop a new sustainable phosphorescent material that could potentially be used in a wide number of applications, from medical imaging and optical ...

A-74 iceberg near collision with Brunt Ice Shelf

Iceberg A-74, approximately 1.5 times the size of Greater Paris, calved from Antarctica's Brunt Ice Shelf earlier this year. Over the last six months, it has remained close to the shelf it broke away from owing largely to ...

Although counter-intuitive, noise can help image reconstruction

People are always eager to obtain clear imaging results through some turbid media, so a variety of methods have been developed to filter out noise and strive to improve the quality of imaging, as if noise is born as the evilest ...
