Reliable high sensitivity FBG geophone for low frequency
Dec 01, 2018A fiber Bragg grating (FBG) based geophone is designed for low-frequency signal detection. It has high acceleration response of about 60 dB re pm/g in a low frequency range of 5–60 Hz. However, the basic sensing principle of stretching FBG requires much more delicate and reliable packaging design and technology.

New seismic sensors for footstep detection and other
Sep 15, 2004We show two different types of seismic sensors: a miniscule, extremely low cost sensor and a bulk sensor. The miniscule, extremely low cost sensor is an electret-based geophone for both seismic and acoustic detection systems. This geophone detects a small size object - i.e. a walking/running/crawling person or a small underwater vehicle-that
