Clinically Informed Intelligent Classification of Ovarian Cancer Cells by Label‐Free Holographic Imaging Flow Cytometry

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Quantitative phase maps of single cells recorded in flow cytometry modality feed a hierarchical architecture of machine learning models for the label‐free identification of subtypes of ovarian cancer. The employment of a priori clinical information improves the classification performance, thus emulating the clinical application of liquid biopsy during ...

Computational Holography

open access: yesInternational Journal of Topology
We establish a comprehensive framework demonstrating that physical reality can be understood as a holographic encoding of underlying computational structures. Our central thesis is that different geometric realizations of the same physical system represent equivalent holographic encodings of a unique computational structure.

AI‐Powered Smart Displays and AR Glasses: Perspectives and Challenges

open access: yesAdvanced Intelligent Systems, EarlyView.
This perspective examines how AI is reshaping smart displays and AR glasses. The latest in image‐quality enhancement, sensor‐integrated display optimization, and physiological sensing in display systems, followed by AI‐assisted AR technologies including waveguide optimization, image compensation, foveated rendering, and multimodal sensing, is discussed.

Generation of Color Images by Utilizing a Single Composite Diffractive Optical Element

open access: yesMicromachines, 2018
This paper presents an approach that is capable of producing a color image using a single composite diffractive optical element (CDOE). In this approach, the imaging function of a DOE and the spectral deflection characteristics of a grating were combined

Lubricant Oil Degradation, Condition Monitoring, and Service Life Estimation: A Review

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
Research framework of the study, integrating lubricant oil degradation, condition monitoring, and service life estimation. ABSTRACT Lubricant oil is often changed on fixed time schedules, even though its real condition depends on load, temperature, and contamination, so good oil is discarded in some cases and degraded oil stays in service in others ...

Three-dimensional spatiotemporal focusing of holographic patterns

open access: yesNature Communications, 2016
Three-dimensional computer-generated holography cannot be implemented with temporal focusing. Here, Hernandez et al. use two spatial light modulators to control transverse- and axial-target light distribution, generating spatiotemporally focused patterns

Review of 3D Imaging by Coded Aperture Correlation Holography (COACH)

open access: yesApplied Sciences, 2019
Coded aperture correlation holography (COACH) is a relatively new technique to record holograms of incoherently illuminated scenes. In this review, we survey the main milestones in the COACH topic from two main points of view.
