Abstract: We present long-range strain measurements using phase-noise-compensated optical frequency domain reflectometry (PNC-OFDR) over 1.5 km with a strain range of 1000 μϵ. In conventional OFDR, ...
Abstract: In practical control systems, limitations such as binary sensing, sensor saturation, and inherent nonlinearities often restrict the available feedback to only the sign of the measured ...
The Artemis II astronauts are making their way back to Earth after the lunar flyby. The crew became the first astronauts in over 50 years to fly around the far side of the moon. They also experienced ...
