Under the support of the MOSTHigher Education SPROUT projects, we have successfully developed a new model of the FOG aiming for the sensing vibrational environment. Our miniaturized integrated optical gyroscope vibration sensors (CIGS), only 250 grams in weighthalf of a business card in footprint, feature high performance (bias stability 1o/hr)cost effectiveness. The sensor is the key to many applications such as the seismic front wave detectionthe vibration monitoring of volcanos, wind turbines, wafer isolation platform, high tension towers, buildings,vehicle bodies.

Our team have developed a new model of the fiber optic gyroscope to work as an integrated-optic seismic sensor. This device is miniaturized by up to 54 compared to commercial products of similar specifications, greatly elevating its scientificapplication values. We have successfully detected a M6.7 earthquakemultiple aftershock events 88 kilometers away from Yilan offshore. The measured data exhibits a higher resolutionmore sensitive to high-frequency vibration modes in contrast to the results from a seismograph at NCU, showing an advance of the seismic science.

With the support of the MOSTthe CAPE of NCU, our team has established the key knowledgecore design technology of the fiber optic sensors,developed a new model of the FOG. The sensor features high performance (bias stability 1 o/hr)cost effectiveness, largely increasing the industrial applicability of this FOG sensor. In 2020, we have successfully detected earthquake events with the sensor. After several scientific verification tests (in such as sounding rocketcube satellite platforms), this sensor is expected to have high application values in the industry.
