On occasion, anomalies in the highly dynamic test data obtained during rocket engine tests may appear. These issues must be investigated, and corrective action is generally mandated before testing resumes; usually only three days are allotted to identify and correct the issues. Spurious signals in...

Conventional Shack-Hartmann Wavefront Sensing requires a point source such as a star to perform wavefront sensing. This software allows one to conduct such sensing using an extended-scene or scene-based image. The software allows a Shack-Hartmann Wavefront Sensor (SH-WFS)...

A characterization software suite was developed to facilitate NASA’s in-flight characterization of commercial remote sensing systems. Characterization of aerial and satellite systems requires knowledge of ground characteristics, or ground truth. This information is...

NASA is one of the top research entities in the world, producing technologies that range from electronics and new materials, to state-of-the-art robotics and sensors. Readers of NASA Tech Briefs get a firsthand look at these new technologies every month. But how many of you have had the chance to go behind the scenes at...

Carbon nanotubes and magnetic molecules are considered building blocks of future nanoelectronic systems. Researchers of Karlsruhe Institute of Technology and French colleagues have combined both components on the atomic level and to build a quantum mechanical system with novel properties.

U.S. Army Research Laboratory scientists in the Sensors and Electron Devices Directorate are currently exploring the field of quantum sensing and are discovering ways in which the Army can benefit from innovations that were once thought impossible.

Scientists from the University of Lincoln and Newcastle University in the U.K. have created a computerized system that allows for autonomous navigation of mobile robots based on the locust’s unique visual system. The work could provide the blueprint for the development of highly...

A team of neuroengineers based at Brown University has developed a fully implantable and rechargeable wireless brain sensor capable of relaying real-time broadband signals from up to 100 neurons in freely moving subjects. Several copies of the novel low-power device, described in the Journal of...
