Researchers from the University of Tartu Institute of Physics have developed a novel method for enhancing the quality of three-dimensional images by increasing the depth of focus in holograms fivefold ...

Photoacoustic microscopy (PAM) is a relatively new imaging technique that uses laser light to induce ultrasonic vibrations in tissue. These ultrasonic vibrations, along with a computer that processes ...

Top: Random Illumination Microscopy (RIM) utilizes random speckle patterns to achieve super-resolution imaging of biological tissues, improving resolution by a factor of two compared to the optical ...

Needle-shaped laser beams (NBs) featuring a long and narrow localization of photons can potentially allow non-diffracting pulses with undistorted temporal profiles. Using this kind of pulse in ...

A hybrid microscope allows scientists to simultaneously image the full 3D orientation and position of an ensemble of molecules, such as labeled proteins inside cells. The microscope combines polarized ...

A completely new type of microscope can take 3D images of cells -- while working in a natural environment. The new technology is significantly faster and better than before and will give researchers ...

Assistant Professor of Biomedical Engineering Yi Xue works on 2P-FOCUS, a new two-photon microscopy system, in her lab. The system promises novel insights into biological features that were once only ...

A programmable LED array provides multi-angle plane-wave illumination, and the transmitted light is collected by microscopic optics and recorded on a camera sensor for subsequent computational ...

If you’ve spent much time looking through a microscope, you know that their narrow depth of field can be a bit challenging to deal with. Most microscopes are designed to only have a very thin slice of ...
