Abstract

A single-component dual-optic paths acceleration seismic geophone based on all-fiber Michelson interferometer is developed, which can detect the acceleration less than 0.01g. In order to obtain the elastic modulus changing of compliant cylinder after rolling fiber, the key component of the sensitive unit, a compressing test and a stretching test are carried out. And at the end of the paper a three-component acceleration seismic geophone based on the single-component one is discussed.
