Optical encoders have been used to measure position, speed, acceleration and motion direction for decades, but now they are finding new applications where high performance and miniaturization are ...

In aviation the term fly-by-wire means that the control surfaces of an aircraft are operated by actuators rather than via cables and rods, with electrical signals transmitting information from the ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

Reduce measurement errors in linear systems to improve reliability, accuracy, and overall machine performance.

The National Science Foundation (NSF) recently awarded ZS Instruments, which is a startup connected to Purdue University, a 2-year/$1 million Phase II Small Business Innovation Research (SBIR) grant ...
