Researchers at the Niels Bohr Institute, University of Copenhagen, have developed a tunable system that paves the way for ...

Apple is investigating new image sensor technology that promises up to 20 stops of dynamic range. Here’s what that actually means.

The Mamyshev oscillator (MO) is a type of fiber laser capable of producing high-energy laser pulses at a tunable repetition ...

image processing image artifacts image filtering Filtering of medical images to remove noise is performed with great care because of the risk of creating artifacts that can lead to misdiagnosis. The ...

An efficient method for tomographic imaging in nuclear medicine is PET. Higher sensitivity, higher spatial resolution, and more accurate quantification are advantages of PET, in comparison to SPECT.

Transforming Noise Maps The new method, Fourier transform noise spectroscopy (FTNS), offers a straightforward, yet powerful, way to analyze the noise affecting qubits by focusing on the qubits’ ...

They captured images at two key points using a color image sensor. The first point was at the focal point of a Fourier transform lens (FTL) — a special type of optical lens designed to precisely ...

If you’ve ever seen a picture where you notice dust particles that are not part of the actual image, you’re probably seeing ‘noise’ in the image. There are many technical reasons for why this happens.
