Abstract

We describe a WEB controlled interrogation system to determine the peak wavelength of the reflection spectra of Bragg gratings. The system is based on a scanning Fabry Perot interferometer, whose electronic control unit has been modified to allow automated operation under external micro-controlled supervision. A micro-controller with embedded WEB server capabilities is used to permit the access through the Internet.
