System and method for measuring radiant energy in gas turbine engines, components and rigs

A system for measuring radiant energy in a gas turbine engine component, comprising:

• a plurality of optical collection elements, wherein each optical collection element is positioned inside one of a gas turbine engine and a gas turbine engine test rig, and wherein each optical collection element is operative to view an area of interest on the gas turbine engine component;
• a plurality of fiber-optic leads in optical communication with the plurality of optical collection elements and extending to outside of the one of the gas turbine engine and the gas turbine engine test rig;
• and
• means for selectively capturing optical data from a chosen fiber-optic lead, wherein the means for selectively capturing the optical data are positioned outside of the one of the gas turbine engine and the gas turbine engine test rig.

A method for measuring radiant energy, comprising:

• coupling first ends of a plurality of fiber-optic leads with a plurality of optical collection elements;
• positioning the optical collection elements in a high temperature apparatus, wherein each optical collection element is operative to view an area of interest;
• coupling second ends of the plurality of fiber-optic leads to a fiber channel selection switch having a plurality of terminals configured to receive the second ends;
• positioning a proximal lens in optical communication with an output port of the fiber channel selection switch;
• choosing a fiber-optic lead for viewing;
• exposing the output port to the chosen fiber-optic lead;
• and
• capturing optical data from the chosen fiber-optic lead via the proximal lens.
