The borescope has a distance sensor for detecting an insertion length when an insertion section of the borescope is inserted through a hole provided in a casing in which a rotor of an engine is housed, an acceleration sensor for detecting an attitude of the insertion section, and distance sensors for detecting two distances from the insertion section to two stator vanes on a stator. The PC compares the attitude and two distances detected in the borescope with the attitude and two distances relating to an inspection image stored in a HDD. When a match occurs therebetween, the PC outputs match information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Blade inspection apparatus and blade inspection method","description":"A blade inspection apparatus has a borescope and a PC.
