Z axis measuring with autofocus works by sensing the contrast level in the image of your part. But many surfaces (such as glass, clear plastic, and mirror-like finishes) create images with extremely low, or worse, nonexistent contrast. How can these be measured? With the Grid Projector accessory from OGP. The Grid Projector is available for SmartScope ZIP, SmartScope Quest, SmartScope ATS, and SmartScope Apex video measuring systems.
Grid Projector Technology The Grid Projector works by projecting a grid pattern onto the surface of the part undergoing inspection. AdvantagesAllows Z axis measurement of previously "un-measurable" surfaces due to insufficient contrast.Improves measurement repeatability.Ideal for parts with translucent layers. Technology | Digital Domesday book unlocked. A rich digital archive of British life in the 1980s has been brought back to life by researchers from the UK and the US. They have developed a way to access the information gathered by the BBC's Domesday project which had been stored on outdated technology. The project was developed by the BBC to create a computer-based, multimedia version of the Domesday Book, marking the 900th anniversary of the 1086 archive.
But the snapshot of in the UK in the mid-1980s was stored on two virtually indestructible interactive video discs which could not be read by today's computers. Preserving the past The team at Leeds University and the University of Michigan in the US say they have now found a way to access this rich digital archive. They have developed software that emulates the obsolete Acorn Microcomputer system and the video disc player. The research is part of the Camileon project. The Domesday Project highlights the problems of digital preservation. Book vs discs. Text Encoding Initiative. Profile. 1. Background A large number of companies and individuals, from a variety of industries, participated in the development of the ICC specification which is designed to provide developers and other interested parties with a clear description of the profile format.
A nominal understanding of color science is assumed, such as familiarity with the CIELAB color space, general knowledge of device characterizations, and familiarity of at least one operating system level color management system. For those who require further background information on colorimetry, refer to An Introduction to Appearance Analysis" by Richard Harold. Device profiles provide color management systems with the information necessary to convert color data between native device color spaces and device independent color spaces.
In addition to providing a cross-platform standard for the actual profile format, the specification also describes the convention for embedding these profiles within graphics documents and images.

University Library Digital Collections: About. Princeton University Digital Library (PUDL) A collection of high-resolution digital images of materials held by the Princeton University Library and its partners. Princeton University Library Finding Aids The Princeton University Library Finding Aids site provides World Wide Web access to finding aids or descriptive inventories for archival records and manuscript collections held within the University Library.
Over 1700 finding aids from the Department of Rare Books and Special Collections, Latin American Ephemera Collections, and the Engineering Library are now available online. The Blue Mountain Project Drawing on Princeton University’s exceptional collections and curatorial and academic expertise, the Blue Mountain Project is a digital thematic research collection of art, music and literary periodicals published between 1848, the year of the European Revolutions, and 1923 – a functional boundary for works presumed to be in the public domain.

Don Williams has brought his decades of experience in digital imaging and extensive worldwide involvement in the digital archiving community together to found Image Science Associates. Don worked as a research imaging scientist for Kodak for 25 years until he left the company in 2006. His work there focused on both digital and traditional imaging practices across a number of disciplines that included reconnaissance, microfilm, consumer photography, and professional photography sectors.
His passion lies in the digital image archiving community and in providing resources by which good imaging can be easily practiced and understood. In partnership with his associates, he has frequently taught and provided educational tools on digital imaging. Don has also published extensively on both technical and policy matters as they relate to digital image fidelity and metrology. Don has a bachelor's and a master’s degree in imaging science from Rochester Institute of Technology. Published Works.
D-Lib Magazine. Spectral Selectivity. Spectral Selectivity Spectral selectivity is a technique for creating images which uses intentionally limited ranges of radiation in the ultraviolet, visible or infrared portions of the spectrum. It has uses in artistic and scientific photography. Early day photographers often needed to work around the inherent spectral sensitivity limitations of the photographic materials available to them. Their photographic materials were sensitive primarily to blue light. Rich blue skies photographed much too light while vegetation and skin photographed too dark. Modern photographic materials are available with sensitive to a wide portion of the spectrum, ranging from 250 nanometers (ultraviolet) to 925 nanometers (infrared).
The topics linked below provide an introduction to spectral selectivity, some technical information for making use of it and a few typical applications. Project Blogs. Digital Imaging in Optical Microscopy - Concepts in Digital Imaging. Concepts in Digital Imaging Technology Charge-coupled devices (CCDs), like microprocessor and memory integrated circuits, are fabricated on silicon wafers in a series of elaborate steps using photolithography to define and build various functional elements within the microcircuitry.
Each wafer contains tens to hundreds of identical devices, each fully capable of producing a single CCD chip for use in digital cameras. This section of the Molecular Expressions Photomicrography Primer contains links to illustrated discussions of important CCD concepts, which are critical in forming a complete understanding of digital imaging techniques. Anatomy of a Charge-Coupled Device - Digital image sensor technology is centered around the semiconductor charge-coupled device, which is fabricated in a manner similar to that used in the production of integrated circuits ranging from microprocessors to memory chips.

Reproduction Accessories. Camera Scanning | dpBestflow. Camera scanning basics With some special hardware, along with some proper techniques, it's possible to make excellent digitizations of film and print originals using a digital camera.
The camera's sensor provides excellent resolution for the scan, even in comparison to dedicated film scanners such as Imacon. A DSLR's built-in anti-moire filter also helps in minimizing the appearence of dust and minor scratches present on the media being scanned. You can compare the relative quality of a file made with an Imacon film scanner and a file made with a Canon 1Ds MkII. We have provided scanned image files for download here. Camera scanning falls into two basic categories: digitizing film and digitizing prints. Print scans Prints are a more straightforward process than film scans, since they are typically larger, and the scan needs only to reproduce the reflected color and tone.
