Learning flat optics for extended depth of field microscopy imaging [PDF]

Nanophotonics, 2023
Conventional microscopy systems have limited depth of field, which often necessitates depth scanning techniques hindered by light scattering. Various techniques have been developed to address this challenge, but they have limited extended depth of field (

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.

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.

Contrast transfer characteristics of the light sword optical element designed for presbyopia compensations [PDF]

Journal of the European Optical Society-Rapid Publications, 2011
The paper discusses the abilities of the light sword optical element (LSOE) for presbyopia compensation. The imaging properties are analyzed by means of the modulation transfer functions and output images of the star resolution test.
