Imaging with parallel ray-rotation sheets.
نویسندگان
چکیده
A ray-rotation sheet consists of miniaturized optical components that function--ray optically--as a homogeneous medium that rotates the local direction of transmitted light rays around the sheet normal by an arbitrary angle [A. C. Hamilton et al., arXiv:0809.2646 (2008)]. Here we show that two or more parallel ray-rotation sheets perform imaging between two planes. The image is unscaled and un-rotated. No other planes are imaged. When seen through parallel ray-rotation sheets, planes that are not imaged appear rotated.

Local light-ray rotation
We present a sheet structure that rotates the local ray direction through an arbitrary angle around the sheet normal. The sheet structure consists of two parallel Dove-prism sheets, each of which flips one component of the local direction of transmitted light rays. Together, the two sheets rotate transmitted light rays around the sheet normal. We show that the direction under which a point ligh...
متن کاملDual filtered backprojection for micro-rotation confocal microscopy
Micro-rotation confocal microscopy is a novel optical imaging technique which employs dielectric fields to trap and rotate individual cells to facilitate 3D fluorescence imaging using a confocal microscope. In contrast to computed tomography (CT) where an image can be modelled as parallel projection of an object, the ideal confocal image is recorded as a central slice of the object correspondin...
متن کاملThe effect of graphite sources on preparation of Photoluminescent graphene nano-sheets for biomedical imaging
Objective(s): Graphene as two-dimensional (2D) materials have attracted wide attention in different fields such as biomedical imaging. Ultra-small graphene nano-sheets (UGNSs) have been designated as low dimensional graphene sheets with lateral dimensions less than few nanometres (≤ 500 nm) in one, two or few layers. Several studies have proven that the process of acidic exfoliation and oxidati...

Background and Aims: Internal derangement of the Temporomandibular joint (TMJ) is the most common form of Temporomandibular disorders, which represents an abnormal internal strucural and functional change of the disk, as well as an abnormal relationship of the disk to the condyle, glenoid fossa and articular eminence when the teeth are in the closed- mouth position. The aim of this study was to...
متن کاملThe Mechanical Properties Evaluation of the Welded Sheets of AA 3105 Aluminum Alloy Using Friction Stir Spot Welding (FSSW)
Friction stir spot welding (FSSW) is a type of solid state welding that is used in the connection of small pieces and light metals such as aluminum alloy especially. The technical problem during melting of aluminum alloys is one of the most important reasons for developing application of friction stir welding for aluminum alloys. In this research, the effects of important processing parameters ...
