We took the traditional geophone and asked, Why has it always been done this way? How can we make it better? Then, we reengineered it with an optical interferometer. Our new optical seismometer is similar in size and shape to the ones you’ve used before, but unlike conventional models, it can record much lower frequencies at a previously unachievable noise floor.
With this sensitivity for lower frequencies and new broadband performance – not to mention omnidirectionality – our seismic sensor enables access to previously inaccessible data, whether your focus is energy exploration or scientific discovery. All this without compromising ruggedness and reliability.
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.
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.
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.
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.
