Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

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 ...

As businesses set new goals and standards for themselves in the new year, they should place extra emphasis on retaining customers and acting upon the valuable feedback they receive. Embracing customer ...
