Collinear, two-color optical Kerr effect shutter for ultrafast time-resolved imaging [PDF]
, 2014 Imaging with ultrashort exposure times is generally achieved with a crossed-beam geometry. In the usual arrangement, an off-axis gating pulse induces birefringence in a medium exhibiting a strong Kerr response (commonly carbon disulfide) which is ...

Wavelet based stereo images reconstruction using depth images [PDF]
, 2007 It is believed by many that three-dimensional (3D) television will be the next logical development toward a more natural and vivid home entertaiment experience. While classical 3D approach requires the transmission of two video streams, one for each view,

Multi-State Image Restoration by Transmission of Bit-Decomposed Data [PDF]
, 2001 We report on the restoration of gray-scale image when it is decomposed into a binary form before transmission. We assume that a gray-scale image expressed by a set of Q-Ising spins is first decomposed into an expression using Ising (binary) spins by ...

Maximum likelihood transmission image reconstruction for overlapping transmission beams [PDF]
1999 IEEE Nuclear Science Symposium. Conference Record. 1999 Nuclear Science Symposium and Medical Imaging Conference (Cat. No.99CH37019), 2000 In many transmission imaging geometries, the transmitted "beams" of photons overlap on the detector, such that a detector element may record photons that originated in different sources or source locations and thus traversed different paths through the object.

Image transmission through an opaque material [PDF]
Nature Communications, 2010 Optical imaging relies on the ability to illuminate an object, collect and analyze the light it scatters or transmits. Propagation through complex media such as biological tissues was so far believed to degrade the attainable depth as well as the resolution for imaging because of multiple scattering. This is why such media are usually considered opaque.

Hyper-Selective Plasmonic Color Filters [PDF]
, 2016 The subwavelength mode volumes of plasmonic filters are well matched to the small size of state-of-the-art active pixels (~ 1 {\mu}m) in CMOS image sensor arrays used in portable electronic devices.

Parallel transmission for ultrahigh‐field imaging [PDF]
NMR in Biomedicine, 2015 The development of MRI systems operating at or above 7 T has provided researchers with a new window into the human body, yielding improved imaging speed, resolution and signal‐to‐noise ratio. In order to fully realise the potential of ultrahigh‐field MRI, a range of technical hurdles must be overcome.

Transmission positron images using imaging plates [PDF]
Applied Surface Science, 2008 Abstract As an image recording medium for transmission positron microscopes, imaging plates are quite useful and powerful. Imaging plates are also quite sensitive and the photon-stimulated luminescence (PSL) is linearly proportional to the positron intensity in six digits (106).

Sensors, 2009 Image transmission using incoherent optical fiber bundles (IOFB) requires prior calibration to obtain the spatial in-out fiber correspondence in order to reconstruct the image captured by the pseudo-sensor. This information is recorded in a Look-Up Table

Joint Early Stopping Criterions for Protograph LDPC Codes-Based JSCC System in Images Transmission
Entropy, 2021 In this paper, a joint early stopping criterion based on cross entropy (CE), named joint CE criterion, is presented for double-protograph low-density parity-check (DP-LDPC) codes-based joint source-channel coding (JSCC) systems in images transmission to ...
