Wide-angle lens

In search of a wide-angle lens.

What do you do to start reading in search of a wide angle lens? Searching the book that you love to read first or find an interesting book that will make you want to read? Everybody has difference with their reason of reading a book. Actuary, reading habit must be from earlier. Many people may be love to read, but not a book. It's not fault. Someone will be bored to open the thick book with sma...

Neuro-Ophthalmology: Through a Wide Angle Lens

“Neuro-ophthalmology” To the casual observer, the name suggests a fi eld limited to the study of the nerves that see and move the eyes. In actuality, neuroophthalmology is a complex subspecialty that merges clinical expertise, fundamental science and applied technology from a variety of related disciplines, including neurology, neurophysiology, developmental anatomy, ophthalmology, visual scien...

Wide-Angle Lens Distortion Correction Using Division Models

In this paper we propose a new method to automatically correct wide-angle lens distortion from the distorted lines generated by the projection on the image of 3D straight lines. We have to deal with two major problems: on the one hand, wide-angle lenses produce a strong distortion, which makes the detection of distorted lines a particularly difficult task. On the other hand, the usual single pa...

Wide Angle Decentered Lens Beam Steering for Infrared Countermeasures Applications

Broadband Wide Angle Lens Implemented with Dielectric Metamaterials

The Luneburg lens is a powerful imaging device, exhibiting aberration free focusing for parallel rays incident from any direction. However, its advantages are offset by a focal surface that is spherical and thus difficult to integrate with standard planar detector and emitter arrays. Using the recently developed technique of transformation optics, it is possible to transform the curved focal su...
