The ring laser resonator generates a laser beam propagating a ring shaped optical path. The fiber Bragg grating is disposed in the ring laser resonator such that the laser beam enters the grating, and has a transmittance distribution characteristic of transmitted light in a wavelength direction, which changes in accordance with vibration of an object. The detection system detects the vibration based on the transmitted light through the fiber Bragg grating."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vibration detection apparatus and vibration detection method","description":"A vibration detection apparatus includes a ring laser resonator, a fiber Bragg grating and a detection system.
