Abstract
Official abstract text for this publication.
Systems and methods for optical narrowcasting are provided for transmitting various types of content. Optical narrowcasting content indicative of the presence of additional information along with identifying information may be transmitted. The additional information (which may include meaningful amounts of advertising information, media, or any other content) may also be transmitted as optical narrowcasting content. Elements of an optical narrowcasting system may include optical transmitters and optical receivers which can be configured to be operative at distances ranging from, e.g., 400 meters to 1200 meters. Moreover, the elements can be implemented on a miniaturized scale in conjunction with small, user devices such as smartphones, thereby also realizing optical ad-hoc networking, as well as interoperability with other types of data networks. Optically narrowcast content can be used to augment a real-world experience, enhance and/or spawn new forms of social-media and media content.
First claim
Opening claim text (preview).
What is claimed is: 1. A receiver comprising: a lenslet array including a plurality of lenslets, each of the plurality of lenslets including a first side and a second side, the first side being convex; a first optical detector array including a plurality of optical detectors, each optical detector of the plurality of optical detectors positioned in a focal plane of the plurality of lenslets, each of the lenslets positioned to concentrate flux collected over the first side of the…
