Measurement of radiation damage on an optical reflector

Optical Radiation Measurement

Radiation damage to polymer optical fibres

Recently, polymer optical fibre dosimeters have been proposed for use in radiation oncology. Prior to clinical acceptance the effects of radiation on the materials involved must be assessed. In this work, the effects of radiation on mechanical strength and power transmission of polymer optical fibres were investigated. The fibres were subject to high energy electrons and photons generated by a ...

Distorted Reflector Antennas: Radiation Pattern Sensitivity to the Surface Distortions

The high-frequency performance of the reflector antennas is mainly limited by the surface. It has been shown that distortions on different regions of the reflector surface can have different effects on the radiation performance. In other words, degradation of the radiation pattern due to the presence of surface distortions is sensitive to the location and behavior of the surface distortion prof...

An Intensity-Modulated Optical Fibre Displacement Sensor with Convex Reflector

A novel intensity-modulated optical fibre displacement sensor with convex reflector technology is described. A common form of the intensity-modulated optical fibre sensor performs its measurement by making use of a pair of straight optical fibres with a plane reflector. The reflected optical signal intensity changes as a function of change in displacement. This paper describes an alternative se...
