Zusammenfassung:	A radiation pyrometer for a gas-turbine engine has a fibre-optic cable with three discrete bundles. At one end of the cable, the bundles, are arranged in a jig with one bundle being positioned centrally, being the other bundles which are of C-shape and located on opposite sides of the central bundle. A converging lens focusses radiation from the turbine blades onto the end of the cable, the ends of the bundle being oriented such that each bundle receives radiation from a different region spaced along the length of the blades. At the other end of the cable, each bundle is connected to a respective detector.
