Compared with other scientific-grade seismic sensors, Silicon Audio’s optical seismometers have substantially higher clip and lower distortion levels. The sensors cover weak and strong motion frequency regimes, enabling users to span both frequency regimes with a single sensor and single data acquisition system (DAQ), rather than multiple sensors and DAQs. For scientific seismic applications, this simplicity is especially ideal for remote installations where portability is a concern. Unlike most other scientific sensors, Silicon Audio’s optical seismometer does not require mass locking. The seismic sensor is configurable for any DAQ. Small size, low power, and ultra-portability make the sensor ideal for high-density array applications and field installations, such as fault studies and earthquake prediction. These features also facilitate rapid deployment needed for earthquake aftershock detection.
The above noise plot demonstrates the low noise and broadband advantages of Silicon Audio's optical seismometers relative to those of state-of-the-art competitors.
Our omni-tilt sensor is optimal for deployment situations in which tilt insensitivity is important. Comparing our omni-tilt sensor (light blue) with 10Hz and 15Hz geophones (green) illustrates our superior performance across a broad frequency range.
Our ultra low noise sensor, while not omni-tilt, delivers the full performance capacity of the optical seismometer technology. When achieving the lowest noise floor is the overriding concern, Silicon Audio's ultra low noise sensor (dark blue) is competitive with state-of-the-art scientific instruments.
