Contemporary imaging air Cherenkov telescopes (IACT) for ground-based very high energy (VHE) gamma ray astronomy have prime focus optical design. Typically these telescopes have a (2−4)◦ wide field of view (FoV). They use f/0.7−f/1.2 optics and provide (3−10) ′ resolution in the FoV. Generally, a well designed telescope that includes more than one optical element will offer some advantages not ...

For a global understanding of the physiological impact of the nuclear hormone 1α,25-dihydroxyvitamin D3 (1,25(OH)2D3) the analysis of the genome-wide locations of its high affinity receptor, the transcription factor vitamin D receptor (VDR), is essential. Chromatin immunoprecipitation sequencing (ChIP-seq) in GM10855 and GM10861 lymphoblastoid cells, undifferentiated and lipopolysaccharide-diff...

A field-of-view-folding approach is proposed to extend the field of view (FOV) of a dispersive imaging spectrometer after introducing several linear arrays of imaging fiber bundles to which to replace the slit. The fiber bundles can flexibly connect fore-optics with a spectrometer to yield an imaging fiber-optic spectrometer (IFOS). The technology of FOV segmenting and folding, which can decrea...

High contrast ratio and wide viewing angle are critical requirements for direct view liquid crystal displays LCDs . Various optical compensation schemes with phase-matched films have been developed to widen the viewing angle of LCDs. A-plate, whose optic axis is located in the plane parallel to film surface, has been widely used in wide-view LCDs. Although positive and negative A-plates are usu...

Overview diagrams are one of the best tools for orientation and navigation in hypermedia systems. However, constructing e ective overview diagrams is a challenging task. This paper describes the Navigational View Builder, a tool which allows the user to interactively create useful visualizations of the information space. It uses four strategies to form e ective views. These are binding, cluster...

We describe a novel robotic endoscope system. It can be used to observe a wide area without moving or bending the endoscope. The system consists of a laparoscope with zoom facility and two wedge prisms at the tip. This new concept produces excellent characteristics as follows. Firstly, it can change the field of view even in a small space. Secondly, it is safe because it avoids the possibility ...

Obtaining a foreground silhouette across multiple views is one of the fundamental steps in 3D reconstruction. In this paper we present a novel video segmentation approach, to obtain a foreground silhouette, for scenes captured by a wide-baseline camera rig given a sparse manual interaction in a single view. The algorithm is based on trimap propagation, a framework used in video matting. Bayesia...
