Spinal Ultrasound Just-in-Time Training Tool

This software facilitates ultrasound imaging of the cervical and lumbar spine by crewmembers in-flight. Lyndon B. Johnson Space Center, Houston, Texas Back pain and injury are recognized risks that can affect the well-being and performance of crewmembers during missions, as well as their long-term health. Spine elongation is a documented effect of microgravity, back pain is a common occurrence in early flight, and the post-flight incidence of spinal injury is higher than the population average. These observations suggest that spinal unloading results in a transition to a new set point for the spine, and causes discomfort and an increased risk of injury.

AEGIS Imaging Software Unearths Mars Rocks

In mid-October, a NASA-developed software called AEGIS was uploaded to the Mars Science Laboratory (MSL) rover. The AEGIS technology, winner of NASA’s 2011 Software of the Year award, will soon allow scientists on the ground to more easily identify interesting rocks and other terrain features on the Red Planet.

Hybrid Technology Advances Laser Material Processing

MultiWave Hybrid Technology* combines multiple laser beams with various wavelengths into a single coaxial laser beam. There are existing systems using two different laser wavelengths independently, but this is the first technology capable of combining multiple wavelengths into a single beam, providing a valuable tool for the development of novel material processing technologies.

Manufacturing OLED Lighting

Organic Light Emitting Diode (“OLED”) lighting panels are thin planar area light sources that are naturally diffuse, low glare, high color rendering, cool to the touch, highly energy efficient and highly controllable. Together with LED light sources, they compose the solid state lighting technologies that are replacing over 100 years of bulb and tube lighting technologies, just as solid state electronics have replaced the bulbs and tubes used in electronic devices such as radios, computers and displays.

‘Internal Fingerprint’ Imaging Offers Deeper Authentication

A new technology developed by researchers from The Langevin Institute (Paris, France) enables subsurface imaging of the finger. The “internal fingerprint,” according to the device’s creators, could provide cheaper, more secure authentication than traditional scanners.

SPIE Photonics West 2016 Preview

The SPIE Photonics West 2016 technical conference and exhibition returns to The Moscone Center in San Francisco, February 13-18, offering attendees the opportunity to explore the latest innovations in lasers, photonics, optics, optoelectronics, biophotonics, biomedical optics, 3D printing and more. As in the past, the event will once again kick off with BiOS, the world’s largest biomedical optics conference, before transitioning into the Photonics West conference and exhibition. Last year’s event hosted more than 21,000 attendees and put the products and services of over 1,250 exhibitors on display. More than 4,800 technical papers will be available to conference participants throughout the week.
