Seismic Sensors

LOW self NOISE

By using optical interferometry, we lowered our sensor’s self-noise to achieve more accurate low noise data across a wider frequency range. In ultra low noise applications, one sensor replaces the need for both a broadband sensor and an accelerometer.

OMNI-TILT

We call it “omni-tilt.” What we mean is that our seismic sensor is 360-degree tilt-insensitive. By eliminating concerns about placement and leveling, our goal is to remove time and expense from sensor deployment in data acquisition.

HIGH CLIP LEVEL

With a high clip level, Silicon Audio’s optical seismometer captures large signals and low-noise signals simultaneously across a wide bandwidth of frequencies. In field applications, one seismometer captures data that previously required multiple sensors.

HOW DOES THE OPTICAL SEISMOMETER WORK?

The traditional geophone has been the industry standard for decades, and for good reason. Silicon Audio took what works and then added an optical component to increase sensitivity and performance, creating a new paradigm for seismic sensors. To understand how our optical seismometer works and what it means for data acquisition, watch this video.
