Abstract
Combustion or steam turbine engines internal areas of interest are inspected by insertion of a foveated image optical head through internal passages within the engine. The foveated image optical head has a central first image portion having higher magnification and smaller field of view that is included within and subtended by a second image portion having a wider field of view and lower magnification. The foveated image optical head facilitates maneuvering the borescope optical head through the turbine engine with the wider field of view second image portion to areas of interest, then performing a more detailed inspection by viewing the higher magnification first image portion. The optical head lenses are in fixed positions, sharing a single, common optical path and a common electronic image sensor. This lens and detector arrangement facilitates construction of a compact optical head, allowing passage through small diameter engine inspection ports.
