Abstract

A fluorescent optical fibre sensor is reported which is capable of monitoring the output of a high intensity microwave powered UV light source as well as being implemented as part of an on-line controller of the lamp output. The sensor is a fibre which has had its cladding removed and replaced with a phosphor doped polymer coating. Spectroscopic measurements are used to show that the control of the lamp temperature is important in determining the optimum output power and dominant emission wavelength. The optical fibre sensor provides a practical means of lamp output control in this harsh electrical environment.
