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 ...

A new miniature incremental encoder brings metrology-grade precision to space-restricted motion systems, offering high ...

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 ...

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 ...

Purdue University alumnus Sergey Zakharov, co-founder and chief technology officer of ZS Instruments, holds an optical encoder wafer created by a prototype of the company’s novel technology. ZS ...
