A planetary scanner (also called an orbital scanner) is a type of image scanner for making scans of rare books and other easily damaged documents. In essence, such a scanner is a mounted camera taking photos of a well-lit environment. Originally, such scanners were expensive and could only be found in archives and museums, but with the availability of cheap, high-resolutiondigital cameras, DIY planetary scanners have become affordable, and for instance are being used by volunteer scan providers for Project Gutenberg.
Flatbed scanners often come in contact with at least part of the object to be scanned. They also require books to be fully opened most of the time (there are some exceptions where the scanning surface ends at the edge of the flatbed scanner, so that a book can be opened partially). Both practices can damage rare books; For example, opening a book 180 degrees can be damaging to its spine. These scanners are also implemented to scan other fragile documents such as old maps. However, planetary scanners that allow the book to open to a full 180 degrees have special features that protect the book binding from being damaged. Many of those scanners are equipped with self-balancing book cradles, gaps for the binding to be placed in, and pressure-sensitive glass controls. It is argued[by whom?] that by opening the book to a full 180 degrees and using scan glass, the scanner is able to capture further into the binding than those using a V cradle.[1]
Planetary scanners tend to touch fewer parts of a book, and provide an option of only opening a book partially.
Single-photon emission computed tomography is a nuclear medicine tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera, but is able to provide true 3D information. This information is typically presented as cross-sectional slices through the patient, but can be freely reformatted or manipulated as required.
A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. Like a flatbed scanner, it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals. Additionally, nearly all barcode readers contain decoder circuitry that can analyse the barcode's image data provided by the sensor and send the barcode's content to the scanner's output port.
An image scanner is a device that optically scans images, printed text, handwriting, or an object and converts it to a digital image. The most common type of scanner used in offices and in the home is the flatbed scanner, where the document is placed on a glass window for scanning. A sheetfed scanner, which moves the page across an image sensor using a series of rollers, may be used to scan one document at a time or multiple, as in an automatic document feeder. A handheld scanner is a portable version of an image scanner that can be used on any flat surface. Scans are usually downloaded to the computer that the scanner is connected to, although some scanners are able to store scans on standalone flash media.
Planetary means relating to a planet or planets. It can also refer to:
Scanner Access Now Easy (SANE) is an open-source application programming interface (API) that provides standardized access to any raster image scanner hardware. The SANE API is public domain. It is commonly used on Linux.
VueScan is a computer program for image scanning, especially of photographs, including negatives. It supports optical character recognition (OCR) of text documents. The software can be downloaded and used free of charge, but adds a watermark on scans until a license is purchased.
A film scanner is a device made for scanning photographic film directly into a computer without the use of any intermediate printmaking. It provides several benefits over using a flatbed scanner to scan in a print of any size: the photographer has direct control over cropping and aspect ratio from the original, unmolested image on film; and many film scanners have special software or hardware that removes scratches and film grain and improves color reproduction from film.
3D scanning is the process of analyzing a real-world object or environment to collect three dimensional data of its shape and possibly its appearance. The collected data can then be used to construct digital 3D models.
A microform is a scaled-down reproduction of a document, typically either photographic film or paper, made for the purposes of transmission, storage, reading, and printing. Microform images are commonly reduced to about 4% or 1⁄25 of the original document size. For special purposes, greater optical reductions may be used.
In multifunction or all-in-one printers, fax machines, photocopiers and scanners, an automatic document feeder or ADF is a feature which takes several pages and feeds the paper one page at a time into a scanner or copier, allowing the user to scan, and thereby copy, print, or fax, multiple-page documents without having to manually replace each page.
Scanography, more commonly referred to as scanner photography, is the process of capturing digitized images of objects for the purpose of creating printable art using a flatbed "photo" scanner with a CCD array capturing device. Fine art scanography differs from traditional document scanning by using atypical objects, often three-dimensional, as well as from photography, due to the nature of the scanner's operation.
Book scanning or book digitization is the process of converting physical books and magazines into digital media such as images, electronic text, or electronic books (e-books) by using an image scanner. Large scale book scanning projects have made many books available online.
Treventus is a company based in Vienna, Austria that was awarded the European ICT prize 2007 in Hanover, Germany for inventing an automatic book scanner, called ScanRobot. This innovative scanner is able to scan entire books automatically, handling the books carefully.
Document cameras, also known as visual presenters, visualizers, digital overheads, or docucams, are real-time image capture devices used to display an object to a large audience, such as a classroom. Document cameras have also been used as replacements for image scanners. Similar to an opaque projector, a document camera is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies. In essence, they are high-resolution web cams, mounted on arms, allowing them to be positioned over a page. The camera is connected to a projector or similar video streaming system, which enables a teacher, lecturer, or presenter to write on a sheet of paper or to display a two - or three - dimensional object while the audience watches. Different types of document cameras/visualizers allow for flexibility in terms of placement of objects. Larger objects, for example, can simply be placed in front of the camera and the camera rotated as needed, or a ceiling-mounted document camera can also be used to create a larger working area.
SilverFast is the name of a family of software for image scanning and processing, including photos, documents and slides, developed by LaserSoft Imaging.
The National Mine Map Repository (NMMR) is part of the United States Department of the Interior (DOI), Office of Surface Mining Reclamation and Enforcement. The NMMR resides in the Pittsburgh suburb of Green Tree, Pennsylvania, and collects and maintains mine map information and images for the entire country, including data and maps of coal mines in the anthracite coal region of northeastern Pennsylvania. The Green Tree facility provides and stores, digitally and in microfilm, over 182,000 maps of abandoned mines. This repository contains maps of mine workings from the 1790s to the present day. It serves as a point of reference for mine maps and other information for both surface and underground mines throughout the United States. It also serves as a location to retrieve mine maps in an emergency. The NMMR provides services ranging from retrieving mine related data for economic analysis to assessing the potential risk associated with underground mining. Through analysis of mine maps and related information, the repository assists private and public sectors in industrial and commercial development, highway construction, and the preservation of public health, safety, and welfare. In addition, they collect, reproduce, and maintain a national inventory of mine maps and supporting documentation for private and public interests.
The CONSOL Energy Mine Map Preservation Project is a project to preserve and digitize maps of underground coal mines in Southwestern Pennsylvania.
The application Barcode Scanner is an Android app, from the open-source project ZXing, that allows an Android device with imaging hardware to scan barcodes or 2D barcodes and retrieve the data encoded. Information encoded often includes web addresses, geographical coordinates, and small pieces of text, in addition to commercial product codes. This Android-based system has similar functionality to a hardware barcode reader.
HP TopShot technology is a digital camera technology that serves as the scanning mechanism on a LaserJet Multifunctional Printer (MFP).
ScanJet is a line of desktop flatbed and sheetfed image scanners originally sold by Hewlett-Packard (HP), later HP Inc., since 1987. It was the first commercially widespread image scanner on the market, as well as one of the first scanners aimed at the small office/home office market. It was originally designed to compliment the company's LaserJet series of laser printers and allowed HP to compete in the burgeoning desktop publishing market of the early 1980s.
