Virtual Microscopy with Extended Depth of Field [PDF]

Digital Image Computing: Techniques and Applications (DICTA'05), 2005
In this paper, we describe a virtual microscope system, based on JPEG 2000, which utilizes extended depth of field (EDF) imaging. Through a series of observer trials we show that EDF imaging improves both the local image quality of individual fields of ...

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 ...

Synthetic Bessel light needle for extended depth-of-field microscopy. [PDF]

Appl Phys Lett, 2018
An ultra-long light needle is highly desired in optical microscopy for its ability to improve the lateral resolution over a large depth of field (DOF). However, its use in image acquisition usually relies on mechanical raster scanning, which compromises ...

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.

Colorful 3D Reconstruction and an Extended Depth of Field for a Monocular Biological Microscope Using an Electrically Tunable Lens [PDF]

Biomimetics
This paper presents a monocular biological microscope with colorful 3D reconstruction and an extended depth of field using an electrically tunable lens. It is based on a 4f optical system with an electrically tunable lens at the confocal plane. Rapid and

Diffusion coded photography for extended depth of field [PDF]

ACM Transactions on Graphics, 2010
In recent years, several cameras have been introduced which extend depth of field (DOF) by producing a depth-invariant point spread function (PSF). These cameras extend DOF by deblurring a captured image with a single spatially-invariant PSF. For these cameras, the quality of recovered images depends both on the magnitude of the PSF spectrum (MTF) of ...
