Extended the depth of field and zoom microscope with varifocal lens

Scientific Reports, 2022
Extending the depth of field (DOF) is especially essential in thick and 3D sample imaging. However, it's difficult to achieve both large DOF and high resolution in a zoom microscope.

E2E-BPF microscope: extended depth-of-field microscopy using learning-based implementation of binary phase filter and image deconvolution [PDF]

Light: Science & Applications, 2023
Several image-based biomedical diagnoses require high-resolution imaging capabilities at large spatial scales. However, conventional microscopes exhibit an inherent trade-off between depth-of-field (DoF) and spatial resolution, and thus require objects ...

Extended-depth of field random illumination microscopy, EDF-RIM, provides super-resolved projective imaging [PDF]

Light: Science & Applications
The ultimate aim of fluorescence microscopy is to achieve high-resolution imaging of increasingly larger biological samples. Extended depth of field presents a potential solution to accelerate imaging of large samples when compression of information ...

Multispectral extended depth-of-field fluorescence microscopy with co-designed meta-optics and neural reconstruction [PDF]

Light: Science & Applications
High numerical aperture fluorescence microscopy provides subcellular resolution, but its depth of field is extremely limited, so thick specimens quickly fall out of focus and typically require axial scanning.

On the extended depth of focus algorithms for bright field microscopy [PDF]

Micron, 2001
Microscopes offer a limited depth of focus which precludes the observation of a complete image of a three-dimensional (3D) object in a single view. Investigations, by a variety of researchers, have led to the development of extended depth of focus algorithms for serial optical slices of microscopic 3D objects in recent years.

Real-time extended depth of field microscopy

Optics Express, 2008
We describe an optical microscope system whose focal setting can be changed quickly without moving the objective lens or specimen. Using this system, diffraction limited images can be acquired from a wide range of focal settings without introducing optical aberrations that degrade image quality. We combine this system with a real time Nipkow disc based

X-ray ptychography with extended depth of field

Optics Express, 2016
Ptychographic X-ray computed tomography is a coherent diffractive imaging method that offers nanometer-scale resolution with quantitative contrast. It offers the possibility to study relatively thick samples by using high energy X-ray photons and exploiting the phase contrast.
