Abstract
A method of inspecting blades of a gas turbine engine for abnormalities includes projecting light from a light source into an illumination area; utilizing a sensor to record data of at least one reflection of the projected light from a blade that is part of a gas turbine engine and is disposed in the illumination area; determining, based on the recorded data, whether the blade is abnormal; and based on the determining indicating that the blade is abnormal, providing a blade abnormality notification. A gas turbine engine is also disclosed.
