Luna Accelerometer Senses Earthquake from 3,000 km Away

Fiber Optic Accelerometer Performs Long-Range Seismometry … and Much More Accelerometers that are part of a vibration event detection development deployment for security applications at Luna’s Atlanta office detected a magnitude 7.1 earthquake, which occurred 18 km west of Searles Valley, California on July 6. Luna’s os7520 optical sensors detected and measured the vibration wave as it arrived in Atlanta 650 seconds later. As part of the…Read More

Geohazard Strain Monitoring Mitigates Risk for Oil Pipelines

Mitigating the risks associated with oil pipeline faults provides increased reliability, reduced downtime and lower maintenance costs, leading to increased revenues. However, pipelines are naturally vulnerable to operational, environmental and man-made issues such as internal erosion and corrosion, mechanical deformation, leaks and encroachments. Compounding the risks, the actual detection and localization of incipient and advanced faults in pipelines is a very difficult, expensive and imprecise…Read More

Measuring Strain and Temperature within 3D Printed Components

Alternative vehicles that utilize 3D printed components face unique challenges with manufacturing and model validation. To advance the understanding of such applications, Local Motors and Luna Innovations embedded high definition fiber optic sensors within structures made with a large-scale area manufacturing machine to provide distributed strain and temperature measurements during and after the printing process. Luna engineers performed experiments to determine how altering the print…Read More

How to Monitor for Rapid Temperature Increases in Battery Cells

The optimal function of Li-ion batteries is confined to restrictive temperature and voltage windows. Internal faults can initiate heating, triggering a positive feedback loop that results in thermal runaway. The worst case scenario resulting from this is an explosive hazard and potential harm to lives. Current monitoring techniques are generally limited to battery management systems that utilize a few discrete single-point sensors. Scaling up of…Read More
