Test of the Practicality and Feasibility of EDoF-Empowered Image Sensors for Long-Range Biometrics

, 2016
For many practical applications of image sensors, how to extend the depth-of-field (DoF) is an important research topic; if successfully implemented, it could be beneficial in various applications, from photography to biometrics. In this work, we want to

The effect of trifocal and extended-depth-of-focus intraocular lenses on optical coherence tomography parameters

Indian Journal of Ophthalmology
Purpose: Optical properties of commonly used multifocal and extended-depth-of-focus (EDOF) intraocular lenses (IOLs) can induce artifacts or changes in optical coherence tomography (OCT) measurements.

Efficacy and comfort following the implantation of extended depth of focus, multifocal, and monofocal intraocular lenses in cataract patients

BMC Ophthalmology
Background Extended depth of focus (EDOF) and multifocal (Multi) intraocular lenses (IOL) can provide a fixed distance of near vision, which may result in some discomfort for patients who prefer different near distances.

Multi-plane encoded light-sheet microscopy with acousto-optics

, 2021
Light-sheet microscopes with an extended depth of field (EDOF) offer a simple but powerful route toward fast volumetric imaging. However, methods for EDOF typically result in a loss of signal-to-noise ratio. Here, we propose a parallelization strategy as
