Improved reliable accelerometers suitable for wide deployment in seismic arrays are needed for earthquake prediction studies. In response to this need Optical Technologies, Inc. (OPTECH) is proposing a fiber-optic accelerometer system that provides the desired performance improvements of broad-band, wide dynamic range, and low power consumption, as well as other significant benefits and features: o Broad-band response (< 0.1 Hz to > 100 Hz) o Wide dynamic range (on the order of 140 to 160 dB) o Low power consumption o Robust construction (no moving parts) o Capability to operate in any orientation o Low maintenance cost o High reliability (no moving parts) o High radiation tolerance (suitable for nuclear plant deployment) o Digital out (in Phase II)
