Designing for 3D Printing

3D printing has progressed over the past decade to include multimaterial fabrication, enabling production of powerful, functional objects. While many advances have been made, it still has been difficult for non-programmers to create objects made of many materials (or mixtures of materials) without a more user-friendly interface.

Camera-Equipped Vehicles ‘See the Light’ in Cities

Imagine if every police car, bus, and garbage truck gathered important infrastructure data as they made their usual routes through the city.In different field tests around the world, re searchers from the Massachusetts Institute of Technology (Cam bridge, MA) mounted a camera-and-sensor system to the tops of vehicles. As the cars traveled up and down streets, sophisticated software recognized and recorded the presence and strength of street lights. The software estimated pole heights and distinguished between the street lamp’s output and other points of illumination.

Developing a Laser System to Decrease the Rate of Neurodevelopment Issues

A fairly new biomedical imaging modality, optoacoustic imaging is based on the use of laser-generated ultrasound. According to the National Center for Biotechnology Information, it is a hybrid method that has emerged over the past two decades, combining the high-contrast and spectroscopic-based specificity of optical imaging with the high spatial resolution of ultrasound imaging.

SPIE Photonics West 2017 Preview

The SPIE Photonics West 2017 technical conference and exhibition returns to The Moscone Center in San Francisco, January 28 through February 2, 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 20,000 attendees and put the products and services of over 1,300 exhibitors on display. More than 4,800 technical papers will be available to conference participants throughout the week (http://spie.org/photonicswest.xml).

Fabricating Optical Mirrors for Use in Outer Space Measurements

There are many ways to manufacture an optic depending on the complexity of the component and the application. From choosing the best substrate, to detailing the numerous operations required to make the optic, all the while considering tight tolerances and other specifications. This article highlights the precision needed to successfully fabricate the mirrors for the Hobby-Eberly Telescope Dark Energy Experiment’s (HETDEX’s) Visible Integral Field Replicable Unit Spectrographs (VIRUS) unit which was designed to measure dark energy in outer space.

Making VR a NASA Reality

NASA researchers want to prove that a virtual reality headset like the Oculus Rift is not just a toy. Josh Kinne, a deputy project manager at NASA Langley Research Center, sees a future role for virtual and augmented reality in the agency’s research and development, CAD design, and data visualization efforts.

Editor's Choice: January 2017

The Convective Heating Improvement for Emergency Fire Shelters (CHIEFS) material can improve the performance of emergency fire shelters for wildland firefighters. The material is based on technology developed for planetary exploration mission heat shields. Fire shelters are the last resort for firefighters trapped by wildfires that block their escape routes. The CHIEFS system can withstand temperatures to 3000 °F. Click here to find out more.
