AVR400 System User Guide
measurement uncertainty An estimate of the uncertainty of a measurement. Usually comprised of instrumental uncertainty and other factors such as procedural uncertainty, and environmental uncertainty. megapixel (MP) A unit of graphic resolution equivalent to one million pixels commonly used to describe the resolution of digital cameras. MetLogix M3 software The M3 video inspection software is advanced metrology software for performing two and three axis measurements in encoder-based systems and field of view systems at high levels of precision and accuracy. M3 software is included with AVR series systems. metrological traceability Property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations, each contributing to the measurement uncertainty. micrometer (µm) One millionth of a meter. MP See megapixel. N National Institute of Standards and Technology (NIST) A physical sciences laboratory and a non-regulatory agency of the United States Department of Commerce. Its mission is to promote innovation and industrial competitiveness. NIST's activities are organized into laboratory programs that include nanoscale science and technology, engineering, information technology, neutron research, material measurement, and physical measurement. NIST See National Institute of Standards and Technology. P
parcentricity
The condition where a feature remain at the optical center of the video image throughout the magnification range of zoom optics.
parfocality
The condition where the video image remains in focus as the magnification is adjusted from highest to lowest with zoom optics. pixel A picture element. Term used to describe the individual light detectors of the CCD sensor in the camera and the individual light emitters of an LCD video monitor.
