Experimental study of z resolution in acousto-optical coherence tomography using random phase jumps on ultrasound and light [PDF]

open access: yes, 2013
Acousto-Optical Coherence Tomography (AOCT) is a variant of Acousto Optic Imaging (also called Ultrasound modulated Optical Tomography) that makes possible to get resolution along the ultrasound propagation axis $z$. We present here new AOCT experimental

Optical Coherence Tomography in Glaucoma

open access: yesJournal of Current Glaucoma Practice, 2012
The optic disk and the RNFL are the principal sites of apparent glaucomatous damage which precedes glaucomatous visual field alterations. RNFL defects are known to precede detection of visual field defects by approximately 6 years. Accurate early detection and monitoring of ONH and RNFL defects has become the prime focus of effective management of ...

5,11‐Di(thiophen‐2‐yl)Tetracene: A Novel Tetracene Derivative for Efficient Singlet Fission with Enhanced Physical and Chemical Stability in Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a new tetracene derivative, 5,11‐di(thiophen‐2‐yl)tetracene (2T‐Tc) is introduced, exhibiting enhanced physical and chemical stability, and retaining favorable singlet fission kinetics with near unity triplet pair yield in thin films.

Speckle in Optical Coherence Tomography

open access: yesJournal of Biomedical Optics, 1999
Speckle arises as a natural consequence of the limited spatial-frequency bandwidth of the interference signals measured in optical coherence tomography (OCT). In images of highly scattering biological tissues, speckle has a dual role as a source of noise and as a carrier of information about tissue microstructure.

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery

open access: yesAdvanced Functional Materials, EarlyView.
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

Choroidal neovascularization associated with combined hamartoma of retina and retinal pigment epithelium: Multimodal imaging

open access: yesIndian Journal of Ophthalmology, 2018
Combined hamartoma of retina and retinal pigment epithelium (CHRRPE) has been considered as a congenital benign entity with evidence of choroidal neovascularization membranes (CNVM) being associated with it in literature.
