Multidimensional en-face OCT imaging of the retina. [PDF]

, 2009
Fast T-scanning (transverse scanning, en-face) was used to build B-scan or C-scan optical coherence tomography (OCT) images of the retina. Several unique signature patterns of en-face (coronal) are reviewed in conjunction with associated confocal images ...

Depth of Field Enhanced Integral Imaging Display System

Photonics
Large depth of field (DOF) is a core pursuit in integral imaging (InIm). In this paper, we propose a DOF-enhanced InIm display system comprising a transmissive mirror device (TMD), a semi-transparent mirror (STM), two 2D displays, and a micro-lens array (

Depth-enhanced mobile robot teleguide based on laser images [PDF]

Mechatronics, 2010
Abstract 3D stereoscopic visualization may provide a user with higher comprehension of remote environment in teleoperation when compared to 2D viewing. Works in the literature have addressed the contribution of stereo vision to improve perception of some depth cues often for abstract tasks, and it is hard to find contributions specifically addressing

Real-time in vivo micromorphology and histopathology of choroidal osteoma using enhanced depth imaging

Indian Journal of Ophthalmology, 2015
Choroidal osteoma is a usually unilateral benign tumor of the choroid composed of mature bone. Optical coherence tomography (OCT) has been used to image osteoma for several years. With the advent of enhanced depth imaging (EDI) feature of spectral-domain

Visibility Enhancement of Underwater Stereo Images Using Depth Image

Journal of Broadcast Engineering, 2012
In the underwater environment, light is absorbed and scattered by water and floating particles, which makes the underwater images suffer from color degradation and limited visibility. Physically, the amount of the scattered light transmitted to the image is proportional to the distance between the camera and the object.

Focusing and Compression of Ultrashort Pulses through Scattering Media [PDF]

, 2011
Light scattering in inhomogeneous media induces wavefront distortions which pose an inherent limitation in many optical applications. Examples range from microscopy and nanosurgery to astronomy.

Sensitivity Enhanced Photoacoustic Imaging Using a High-Frequency PZT Transducer with an Integrated Front-End Amplifier

Sensors, 2020
Photoacoustic (PA) imaging is a hybrid imaging technique that can provide both structural and functional information of biological tissues. Due to limited permissible laser energy deposited on tissues, highly sensitive PA imaging is required.

Multimodal Magnetic Resonance and Near-Infrared-Fluorescent Imaging of Intraperitoneal Ovarian Cancer Using a Dual-Mode-Dual-Gadolinium Liposomal Contrast Agent. [PDF]

, 2016
The degree of tumor removal at surgery is a major factor in predicting outcome for ovarian cancer. A single multimodality agent that can be used with magnetic resonance (MR) for staging and pre-surgical planning, and with optical imaging to aid surgical ...
