Our approach to extending the depth of field utilizes the concept of point spread function (PSF) engineering to greatly increase the axial range clearly imaged in a single exposure. The basic concept ...

a, An axi-symmetric binary phase filter (BPF) and image reconstruction network are jointly learned through the physics-informed neural network. The learned BPF is fabricated and inserted in a pupil ...

Microscopic evaluation of resected tissue plays a central role in the surgical management of cancer. Because optical microscopes have a limited depth-of-field (DOF), resected tissue is either frozen ...

Microscopy plays a pivotal role in modern biomedical research, enabling the visualization of fine structures in complex ...

The new TESCAN S8000 microscope has not sacrificed the macroscopic analysis. The TESCAN S8000 features the BrightBeam™ SEM column technology. The electron optics is based on a combination of ...

Classic design: the Schmidt objective produces detailed images of neurons in a mouse brain. (Courtesy: Anna Maria Reuss (USZ) & Fabian Voigt (UZH)) Researchers in Switzerland have built what they ...

It might seem like a paradox that you want a dark field to see things with an expensive microscope. As [IMSAI Guy] explains, a dark field microscope doesn’t make the subject dark. It makes the area ...

Brightfield microscopy has been widely used for hundreds of years, while reflection contrast microscopy is relatively new technology. As one of the earliest and simplest microscopy techniques, ...
