- W2077706235 abstract "A digital seismic measuring chain is an electromechanical system able to record the lowest natural ground motionsobservable on Earth but also to measure signals from largest earthquakes. Its cornerstones are an inertial seismometerand a digitizer. As equipments available on the market don't answer to all seismological applications CEA/DAM/DIF(Commissariat a l'Energie Atomique/Direction des Applications Militaires/ Ile De France) is interested in, it hasdeveloped the adequate digital seismic measuring chains. Today, the technologies used have reached their maturity. Newsensing techniques need to be developed.Optical sensors are now widely used in vibrometry and motion measurements. Such devices generally use interferometryand frange interpolation to achieve high resolution with a large dynamic range. We have developed macroscopicprototype digital motion transducer from a Michelson interferometer in order to evaluate the potential of this technologyfor seismological applications.First, tests were carried out to validate the operation of these transducers and to estimate their main characteristics forseismological applications. We focused on transducer motion range, intrinsic noise and temperature sensitivity.We have evaluated and compared performances of such interferometers in visible (632 nm) and in infrared (1550 nm)range. Then, we have experimentally evaluated noise sources in displacement measurement. Last, we designedMichelson interferometer with integrated optics component with a company which is specialized in integrated optics.Expected results are presented in this document." @default.
