Air-Data System Detects Aircraft Icing

Michigan Aerospace Corporation (MAC) has begun work on a Phase I Small Business Innovation Research (SBIR) contract with NASA’s Langley Research Center. The contract, “RIDES: Raman Icing Detection System,” extends MAC’s present aircraft-based optical airdata system technology — which uses ultraviolet laser light to measure air speed, direction, temperature, and density — to also detect conditions aloft when ice is likely to form, enabling a multi-hazard sensing capability.

Elemental Scanning Devices Authenticate Works of Art

A scanner used to analyze spacecraft components can help identify a real Van Gogh. Are the shoes you’re wearing really made of leather? Is the table nearby made of wood? How can you be sure? These questions may seem trivial in everyday life, but knowing the precise chemical makeup of spacecraft components is a crucial part of quality control and can help ensure a successful mission. And learning that the paint on a canvas was produced using modern materials could be what prevents a museum from spending $10 million on a forgery.

3D Visualization Technologies: Seeing a World of Opportunity

Industries as diverse as architecture, engineering, construction, advertising, and medical have all incorporated an array of 3D visualization technologies into their design, development, and production processes. A rapidly expanding library of 3D modeling tools, 3D content, and 3D printing materials have made design more cost-effective and expedited the product-to-market process. But how exactly do 3D visualization technologies work? Taking a closer look at the science behind the innovation reveals a striking convergence in which state-of-the-art research processes meet a growing understanding of visual communication.

Precision Electronics and Laser Optics Expand Thermal Applications

Thermal imagers allow a user to see an object’s heat signature, and heat provides an entirely different set of performance data than the visible spectrum available to the naked eye. A fully radiometric camera will calculate a temperature value for every pixel seen on screen. The technician uses the thermal colors on screen to look for differences in temperature, between previous states or like components, without actually coming into direct contact with the device under test.

Ophthalmology Imaging: The Importance of Color Reproduction

Lumenera recently partnered with an ophthalmology diagnostic device manufacturer that required a camera for integration into its product. The goal was to obtain sharp retinal fundus images with accurate color reproduction for documentation, sharing, and storage of their results. A date stamp was also needed for later review and diagnosis.
