high resolution


Modern cameras have resolutions that photographers of the last decade could only dream of – things have come a long way in a very short time. The standard is now believed to be around the 30MP mark, while it’s not uncommon to find full-frame mirrorless cameras with sensors above 50MP. With such a high number …

Biology researchers at Indiana University have developed an integrated system that merges high-resolution optical coherence microscopy (HR-OCM) with confocal scanning dual-channel fluorescence microscopy (DC-SCFM) to enable a 3D visual assessment of cellular activities involved in pupil development and pathological conditions. . Still in its experimental stages, this dual-modality 3D system simultaneously co-registers reflectance and fluorescence …

The curvy young stellar jet, MHO 2147, snakes lazily through a star field in this image captured from Chile by the Gemini International Observatory, a program of NSF’s NOIRLab.

Meandering stellar jets meander lazily through a star field in new images captured from Chile by the Gemini International Observatory, a program of NSF’s NOIRLab. The gently curved stellar jets are the outflow of young stars, and astronomers suspect that their sideways appearances are caused by the gravitational pull of companion stars. These crystal-clear observations …

Despite considerable progress, modern image editing systems often struggle with large missing portions, complex geometric patterns and high resolution images. Recently, Roman Suvorov et al. came up with a SOTA technique called LaMa, which can mask any scale of the object in a given image and return a fetched image excluding the object we masked. …

“When you have satellites in space, you can take a photo anywhere in the world, not just your backyard or your area, anytime, and that ability is quite deep and extraordinary, ”says Robbie Schingler, co-founder and director of the strategy of the satellite data company Planet Laboratoires. Schingler sees the company as an agent of …

October 11, 2021 (Nanowerk News) The first scientific analysis of images taken by NASA’s Perseverance rover has now confirmed that Mars’ Jezero Crater – which today is a dry, wind-eroded depression – was once a calm lake, regularly fed by a small river about 3.7 billion years ago. The images also reveal evidence that the …

Scientists at the European Molecular Biology Laboratory (EMBL) have combined AI algorithms with light-field microscopy and light-sheet microscopy. The AI-enhanced hybrid approach reduced the time it took to process images – from days to seconds – and ensured the resulting images were crisp and clear. Light-field microscopy captures large 3D images that allow researchers to …

Astronomers recently released the most comprehensive images ever of galaxies beyond our own. These images were created from data collected by the Low-Frequency Array (LOFAR). Additionally, these images were made possible because the international nature of the collaboration pushes the boundaries of what we know about galaxies and supermassive black holes. These most detailed galaxy …

CAMBRIDGE, Mass., July 28, 2021 – A custom-built near-field infrared (IR) nanoscope and spectroscope by an MIT research team can quickly and economically probe the characteristics of various materials at the nanoscale. Also known as a scattering-type scanning near-field optical microscope, or s-SNOM, the tool can identify internal properties of a material, such as how …

To create high-resolution 3D images of tissues such as the brain, researchers often use two-photon microscopy, which involves shining a high-intensity laser at the sample to induce fluorescence excitation. However, scanning deep into the brain can be difficult because light scatters from the tissues as it goes deeper, making images blurry. Two-photon imaging is also …
