Реферат: An optical fibre (1) infrared radiation sensor comprises a plurality of spaced detection zones (11, 12) arranged along its length. Each detection zone (11, 12) comprises: - a reference zone (3) comprising a reference grating (3'); and - an IR detection zone (2) arranged to have a greater absorption to infra red radiation than the reference zone (3)and comprising (i) an infrared absorber (21) which increases its temperature when subjected to infrared radiation and (ii) an associated IR detection zone grating (2') provided at the fibre adjacent to the reference grating (3') which provides a temperature sensitive detection zone which is sensitive to an increase in temperature of the infrared absorber (21).
