Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...

To build an optical isolator one needs a mechanism to break Lorentz reciprocity 9,10. The standard approach is to use magneto-optical materials that possess an asymmetric permittivity tensor ...

In Industrial motor or servo control applications, accurate current measurement is a critical as part of the control loop. Not only has the current measurement need to be as accurate as possible, it ...
