ImageJ is a Java-based image processing program developed at the National Institutes of Health and the Laboratory for Optical and Computational Instrumentation (LOCI, University of Wisconsin). [ 2 ] [ 3 ] Its first version, ImageJ 1.x, is developed in the public domain , while ImageJ2 and the related projects SciJava , ImgLib2 , and SCIFIO are ...
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.

Digital instrument meter with digital display. Only numbers are shown at a digital display. Analogue instrument meter with digital display. Only numbers are displayed, but through a mechanical or electro-mechanical display (today very rare but has existed for clocks, certain Doppler meters and informational screens at many stations and airports)
Digital image correlation and tracking is an optical method that employs tracking and image registration techniques for accurate 2D and 3D measurements of changes in images. This method is often used to measure full-field displacement and strains , and it is widely applied in many areas of science and engineering.
In machine-shop terminology, the complete digital read-out system (consisting of a computer, axis-position encoders, and a numeric display) is referred to by the acronym DRO. Such a system is commonly fitted to machines in today's shops, especially for metal working — lathes, cylindrical grinders, milling machines, surface grinders, boring ...
The dieter's problem: this scale can only resolve weight changes of 0.2 lbs, even though the digital display looks as if it could show 0.1 In the science of measurement , the least count of a measuring instrument is the smallest value in the measured quantity that can be resolved on the instrument's scale.

The micrometer is showing a measurement of 7.145 mm ± 0.005 mm. Legend: Anvil: part that the spindle moves toward, and that the sample rests against; Spindle: moved by the thimble towards the anvil; Ratchet stop: limits applied pressure by slipping at a calibrated torque; Sleeve: stationary linear scale with 0.5 mm resolution
