Real-Time Fiber Optic Strain and Shape Sensing (FOSS) Technology

Researchers at NASA’s Dryden Flight Research Center have patented a lightweight, fiber optics interrogation algorithm that can be used for real-time wing shape sensing, temperature, and strain measurements. The virtually weightless fiber Bragg grating sensors, along with NASA’s efficient algorithms, provide strain data that enable precise calculations of shape, stress, stiffness (bending and torsion), temperature, pressure, strength, and operational loads in real time. Unlike conventional strain gauges which are heavy, bulky, and spaced at distant intervals, NASA’s fiber optic sensors are small, non-intrusive, easy to install, and provide high-resolution (0.5-inch) strain measurements that are much more precise than ever before. This critical, real-time monitoring capability detects changes during operation without affecting the intrinsic properties of the structure and without the need for structural modifications.

Designing Graphics for Safety Critical Systems Using OpenGL SC

Some implementations for graphics in embedded systems don’t fly in safety-critical uses. For an application to be DO-178B/C certified, all its components must be certifiable. Requirements such as determinism, SWaP, radiation hardening, and others make the situation even more challenging for designers, limiting possibilities.

Eliminating Errors and Improving Accuracy in Motion Control and Machine Systems

Presenters will cover how to identify and eliminate contributors to and causes of positioning errors in motion control and machine systems. Mechanical, electronic, position feedback, and thermal issues will be addressed. The Webinar will also present strategies for elevating accuracy, including encoder influences on the motion control loop to get precise position and part accuracy, and how to design absolute position feedback systems using encoders and optimizing data interfaces.

NASA Scanning Technology Creates 3D Maps of Surface Flaws

The High-Speed 3D Laser Scanner, developed by NASA’s Ames Research Center, creates a highly accurate 3D map of a surface for measuring "flaws" or deviations on that surface. It was originally designed to scan Space Shuttle Orbiter thermal tiles to accurately detect and measure the depth, area, and volume of flaws on the tiles. Scans are accomplished at high speed, with the most accurate scan taking less than 3 seconds. The 3D scanner is small, light, and portable. The instrument connects to a portable PC that displays a 3D map of the scanned surface while scanning, identifies flaws on the surface, and displays the flaw measurements.
