Open Source Software

Bitplane (Belfast, Northern Ireland) announced that its proprietary IMS file format would become Open Source. The IMS file format is based on Hierarchical Data Format (HDF5), which is designed to work with huge multidimensional data and is optimized to allow extremely fast visualization of huge volume data. To facilitate this, the format stores not only the original image data but also lower resolution versions of the original data. This allows the visualization software to load the resolutions which match those of the screen.

Thermal Imaging Cameras See Through the Smoke

Figure 2. A firefighter uses FLIR’s K2 to navigate safely and stay better oriented during response missions.Scientists, researchers, automation specialists, electrical and building professionals, and security specialists use thermal imaging cameras (TICs) to discover hidden heat patterns and gain new insights in their fields of expertise. Thermal imaging technology, however, can also save lives. Firefighters use thermal imaging cameras every day to see through smoke, locate and rescue victims, identify hot spots, navigate safely, and stay better oriented during response missions.

Stereoscopic Planar Laser-Induced Fluorescence Imaging for Time-Resolved 3D Movies in Hypersonic Flow

This technique may be useful in applications where time-resolved visualization of unsteady, high-speed flows is needed, such as detonations, supersonic combustion systems, and explosions.

Langley Research Center, Hampton, Virginia

Understanding and predicting transition from laminar to turbulent flow in hypersonic boundary layers is an active and important field of research because transitional and turbulent heating can be four or more times higher than laminar heating on hypersonic vehicles, including the Orion Crew Exploration Vehicle (CEV).

Modified-Wolter-Schwarzschild X-ray Telescope

Goddard Space Flight Center, Greenbelt, Maryland

X-ray survey missions require nested grazing incidence telescopes with a large field of view (1° or larger) and moderately high resolution across the field of view. This cannot be accomplished using flat focal plane detectors. The telescopes have excellent on-axis resolution, but unacceptable resolution at the edge of the field of view. The aberrations need to be optimized and correctly balanced to improve the telescope optical performance across the field of view.

Machine Vision-Based Pose Estimation System

This system uses ellipse detection for spacecraft autonomous rendezvous and docking (AR&D).

Goddard Space Flight Center, Greenbelt, Maryland

During on-orbit servicing of non-cooperative satellites, the relative position of the satellite with respect to the servicing vehicle is needed. Non-cooperative satellites do not have devices to assist the pose estimation (such as markers or reflector), so a system that uses the natural features of the satellite to determine its pose needs to be developed.

Solar Doppler Shift-Based Solar Tracker

Potential applications may be in terrestrial solar thermal collectors.

NASA’s Jet Propulsion Laboratory, Pasadena, California

This solar tracker integrates a camera with a field of view (FOV) large enough to easily image the entire solar disc — co-boresited with a narrow-band spectrometer that measures the frequency of a Doppler shifted line — with an algorithm designed to drive zero Doppler shift rotation axis of the Sun.
