A common approach to measuring distance or angle in a rotating system is by using an incremental encoder or resolver. The majority of industrial applications, such as machines or drives, are dominated ...

Learn how 4D digital holographic microscopy provides real-time, non-contact measurement of MEMS micromirror deformation, ...

Precision instruments often contain specialized components that are essential to their function, but nearly impossible to replace if they fail. [Andre] had just such a problem with an optical ...

Several applications require a through shaft which prevents from using the basic principle which is angular position measurement using variation of magnetic field amplitude induced by the displacement ...

The “mils” in a mil-dot scope refer to milliradians, which is a measurement of angle. If you picture a mil as an ice cream cone, with the tip originating at the shooter’s eye and an open end that gets ...
