Extended depth-of-focus wavefront design from pseudo-umbilical space curves.

, 2023
Designing extended-depth-of-focus wavefronts is required in multiple optical applications. Caustic location and structure analysis offer a powerful tool to design such wavefronts. An intrinsic limitation of designing extended-depth-of-focus wavefronts is

How Reliable Is Pyramidal Wavefront-Based Sensor Aberrometry in Measuring the In Vivo Optical Behaviour of Multifocal IOLs?

Sensors, 2023
Cataract or refractive lens surgery, along with the implantation of multifocal intraocular lenses (MF-IOL), enables a complete range of functional far, near and intermediate vision.

Extended depth of focus imaging: a review [PDF]

Journal of Photonics for Energy, 2010
We review approaches for extending the depth of focus of different imaging systems including the human vision system. Approaches involving digital postprocessing as well as different types of all-optical techniques are discussed.

Estimating scale using depth from focus for mobile augmented reality. [PDF]

, 2011
Whilst there has been considerable progress in augmented reality over recent years it has principally been related to either marker based or apriori mapped systems which limits its opportunity for wide scale deployment.

Inverse designed extended depth of focus meta-optics for broadband imaging in the visible

, 2021
We report an inverse-designed, high numerical aperture (∼0.44), extended depth of focus (EDOF) meta-optic, which exhibits a lens-like point spread function (PSF).

Laboratory evaluation of the optical properties of two extended-depth-of-focus intraocular lenses

BMC Ophthalmology, 2020
Background To experimentally compare the optical performance of two different Extended-Depth-of-Focus (EDOF) intraocular lenses (IOLs) using a standardized optical bench set-up. Methods In this experimental study, following IOLs were assessed: the TECNIS®
