The reflection direction of the first optical element and the reflection direction of the second optical element are arranged at an angle along the circumferential direction of the test object. The light reflected by the first optical element is irradiated at a position different than light reflected by the second optical element, and the laser irradiation positions of the light reflected by the first and second optical elements are different in the axial direction and the circumferential direction of the test object."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Laser-based maintenance apparatus using ultrasonic wave detection for flaw analysis and repair","description":"A laser maintenance apparatus including a laser irradiation device which includes a first optical element for irradiating detection laser light on a test object to detect an ultrasonic wave; a second ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8497986","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
