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.

Trade-Off Asymmetric Profile for Extended-Depth-of-Focus Ocular Lens

Photonics, 2022
We explore the possibility of extending the depth of focus of an imaging lens with an asymmetric quartic phase-mask, while keeping the aberration within a relatively low level.

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.

Microscope with extension of the depth of field by employing a cubic phase plate on the surface of lens

Results in Optics, 2021
An incoherent optical system with wavefront coding extends the depth of field (DOF) by employing a cubic phase plate (CPP). We designed a digital microscope with a CPP in the aperture stop and on the surface of the lens, which extended the DOF.

Extended Depth-of-Field of a Miniature Optical Endoscope Using Wavefront Coding

Applied Sciences, 2020
Endoscopic imaging is an indispensable tool for visual inspection of surfaces in hard-to-access places. The conventional optical endoscope only enables imaging the regions that lie close to the focal plane, and therefore improving the depth of field (DOF)
