Extraordinary transverse magneto-optical Kerr effect in a superlens [PDF]

open access: yes, 2013
It has been shown that a slab of a negative index material can behave as a superlens enhancing the imaging resolution beyond the wavelength limit. We show here that if such a slab possesses in addition some magneto-optical activity, it could act as an ...

In vivo optical imaging of physiological responses to photostimulation in human photoreceptors [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2016
Significance Using a full-field optical coherence tomography system, we measured changes in the time that light requires to pass through photoreceptor outer segments, when the retina is stimulated by a light pulse.

Wide-field optical sectioning for live-tissue imaging by plane-projection multiphoton microscopy [PDF]

open access: yes, 2011
Optical sectioning provides three-dimensional (3D) information in biological tissues. However, most imaging techniques implemented with optical sectioning are either slow or deleterious to live tissues.

Fundamentals of Optical Imaging [PDF]

open access: yes, 2008
Optical imaging techniques offer simplistic while highly sensitive modalities for molecular imaging research. In this chapter, the major instrumental necessities for microscopic and whole-animal imaging techniques are introduced. Subsequently, the resulting imaging modalities using visible or near-infrared light are presented and discussed.

Noninvasive real-time characterization of non-melanoma skin cancers with handheld optoacoustic probes

open access: yesPhotoacoustics, 2017
Currently, imaging technologies that enable dermsurgeons to visualize non-melanoma skin cancers (NMSC) in vivo preoperatively are lacking, resulting in excessive or incomplete removal.

Noninvasive depth estimation using tissue optical properties and a dual-wavelength fluorescent molecular probe in vivo [PDF]

open access: yes, 2017
Translation of fluorescence imaging using molecularly targeted imaging agents for real-time assessment of surgical margins in the operating room requires a fast and reliable method to predict tumor depth from planar optical imaging.

Imaging Velocity Fields Analysis of Space Camera for Dynamic Circular Scanning

open access: yesIEEE Access, 2020
Compared with traditional push-broom imaging, the space camera that performs the new circular scanning imaging can effectively enlarge the imaging area and obtain high-resolution images. However, the imaging velocity fields of space camera will seriously

Growth factor dependent changes in nanoscale architecture of focal adhesions

open access: yesScientific Reports, 2021
Focal adhesions (FAs) are flat elongated structures that mediate cell migration and link the cytoskeleton to the extracellular matrix. Along the vertical axis FAs were shown to be composed of three layers.

Single-shot ultrafast optical imaging.

open access: yesOptica, 2018
Single-shot ultrafast optical imaging can capture two-dimensional transient scenes in the optical spectral range at ≥100 million frames per second. This rapidly evolving field surpasses conventional pump-probe methods by possessing the real-time imaging ...
