Polarization‐Sensitive Holotomography for Multidimensional Label‐Free Imaging and Characterization of Lipid Droplets in Cancer Cells

open access: yesAdvanced Science, EarlyView.
Polarization‐sensitive holotomography (PS‐HT) enables label‐free 3D imaging and quantitative analysis of lipid droplets by exploiting their intrinsic birefringence. Applied to prostate cell models, PS‐HT reveals glucose‐induced lipid accumulation in cancer cells and achieves near‐perfect classification of healthy and cancerous states.

Off-axis transmission holographic system for recording aquatic particles [PDF]

open access: yes, 1996
We describe a holographic system for recording particles suspended in water. The hologram plate is located in air, separated from the test tank by an air/glass/water boundary. The holographic emulsion is therefore unaffected by adverse aquatic conditions

Aging as a Loss of Goal‐Directedness: An Evolutionary Simulation and Analysis Unifying Regeneration with Anatomical Rejuvenation

open access: yesAdvanced Science, EarlyView.
The paper proposes that the root cause of aging is the loss of anatomical goal‐directedness after development. Using evolutionary neural cellular automata simulations, the authors show that after the organism has reached its developmental homeostatic setpoint (the adult morphology), the absence of target state to pursue leads to a drifting anatomical ...

An Acquisition Method for Holographic Display

open access: yesImaging and Applied Optics 2014, 2014
It is well known that holographic display can provide 3D scenes with continuous viewpoints and free of accommodation-convergence conflict. So far most of the research in this area focuses on the display end, leaving the acquisition end merely explored. For holographic content acquisition, one needs to capture the scene in 3D.

Direct Nucleation of Hierarchical Nanostructures on Plasmonic Fiber Optics Enables Enhanced SERS Performance

open access: yesAdvanced Science, EarlyView.
An unconventional synthesis strategy enables the direct growth of shape‐tunable nanostructures, from multi‐dot to multi‐arm designs, on silica optical fiber tips. This breakthrough boosts the sensing power of plasmonic fiber‐optic probes and unlocks new possibilities for large‐scale, in situ nanofabrication on silicate‐based substrates, including ...

Visual perception of Fourier rainbow holographic display

open access: yesETRI Journal, 2019
The rainbow hologram provides views of reconstruction with rainbow color within a large viewing zone. In our recent paper, a Fourier rainbow holographic display using diffraction grating and a white‐light LED source was introduced. In this technique, the
