BEIJING, June 1, 2020 — To reduce noise in a thin, lensless camera, researchers from Tsinghua University and MIT have built an imaging system with a Fresnel Zone Aperture (FZA). In addition to introducing an optical Fresnel element into the camera, the researchers used a compressive detection algorithm to improve the quality of the reconstructed …

Watch Video: Home Photography Ideas – Use a prism to take dazzling images A simple prism is designed to split the spectrum of white light into separate wavelengths. When white light passes through, we can see the visible spectrum of red, orange, yellow, green, blue, indigo, and violet. This stimulated the interest of the Romans …

Electrical engineers at Duke University have developed an inexpensive method …

Hyperspectral imaging has the potential to better detect skin cancer to improve patient survival rates. Skin cancer is one of the most common types of cancer and in some parts of the world it is becoming increasingly common. Most skin cancers are not life-threatening, but one particular type called malignant melanoma is known to be …

LANCASTER, England, January 15, 2020 – Nearing the completion of its 13-year mission, which ended in September 2017, the Cassini spacecraft completed a series of orbits that brought it closer to Saturn than ever before. Flying over the planet’s polar regions at low altitude, Cassini’s ultraviolet camera was able to observe Saturn’s auroras with unprecedented …

Spectral confocal microscopy was used to visualize neurons using silver and gold cell labeling. The development enables imaging of archived tissue samples, which could aid long-term clinical research efforts and the diagnosis of cancer and neurological disorders. Staining neurons with silver began in the 1800s, and now researchers at the University of Minnesota and Agnes …

A miniaturized hyperspectral device was developed as an add-on to a standard camera and could be used to reuse a camera to generate hyperspectral images and video for a range of applications. The device uses compressional sampling techniques to capture signals and images from far fewer samples or measurements than the traditional sampling theorem that …

These fascinating colorized photos bring the men and woman who murdered Abraham Lincoln to life. They show the conspirators handcuffed before their trial next to what is believed to be the last photo of Lincoln before his death. Another colorized photo shows the moment four of the plotters were hanged in front of a crowd …

By Angelica Coleman Editor-in-chief It’s easy to see why color images are more ideal than grayscale images. However, in the world of microscopy, producing color images is often a complicated task. Source: Adams et al./Cell Chemical Biology 2016 Electron microscopy is a high-power method used to observe atomically thin materials and cells. The microscope produces …

We’re still a few hours away from receiving confirmation that New Horizons experienced its Pluto flyby, but that doesn’t mean the team behind the spacecraft is twiddling its thumbs. This afternoon, the team, led by lead investigator Alan Stern, released this exaggeratedly colored savage image of Pluto and its larger moon, Charon. It’s a very …

Just four days after entering orbit, the European Space Agency’s Sentinel-2A satellite delivered its first images of Earth. Acquired on June 27, 2015, this first image of Sentinel-2A covers the Po Valley, framed by the Alps to the north and the coastal mountains of France and Italy to the south. Scratches observed over water are …

Sentinel-2A sees Italy as a patchwork of bright colors. Copernicus data (2015) / ESA Earth is already a colorful place, but it becomes surreal when viewed through the eyes of the Sentinel-2A satellite of the European Space Agency. Where human eyes could see swaths of green across the Po Valley in northern Italy, Sentinel-2A sees …
