Planetary scanner

Last updated

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-resolution digital 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.

Barcode reader electronic device that can read and output printed barcodes to a computer

A barcode reader is an optical scanner that can read printed barcodes, decode the data contained in the barcode and send the data to a computer. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating for optical impulses into electrical signals. Additionally, nearly all barcode readers contain decoder circuitry that can analyze the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.

Image scanner device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image

An image scanner—often abbreviated to just scanner, is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image. Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications. Mechanically driven scanners that move the document are typically used for large-format documents, where a flatbed design would be impractical.

Film scanner Device for scanning photographic film

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 device that analyses real-world objects or environments to collect data on their shape and possibly their appearance

3D scanning is the process of analyzing a real-world object or environment to collect data on its shape and possibly its appearance. The collected data can then be used to construct digital 3D models.

Microform Forms with microreproductions of documents

Microforms are scaled-down reproductions of documents, typically either films or paper, made for the purposes of transmission, storage, reading, and printing. Microform images are commonly reduced to about one twenty-fifth of the original document size. For special purposes, greater optical reductions may be used.

Automatic document feeder

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 technique of capturing still images using a flatbed scanner

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 Process of converting physical media into digital media

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.

Floating hinge Type of hinge

A floating hinge is a hinge that, while able to behave as a normal hinge, enables one of the objects to move away from the other - hence float. In effect the hinge allows for two parallel axes of rotation, one for each object joined by the hinge, and each axis can be moved relative to the position of the other.

National Mine Map Repository

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.
