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.

NASA Tests New Jet Engine Design

NASA is helping the aircraft industry increase fuel efficiency with a new engine design. In its 8 × 6-foot wind tunnel, Glenn Research Center engineers are testing a new fan and inlet design, called a propulsor, that could increase fuel efficiency by four to eight percent more than the advanced engine designs airlines are beginning to use.

The next time you place your coffee order, imagine slapping onto your to-go cup a sticker that acts as an electronic decal, letting you know the precise temperature of your coffee. Engineers at MIT have invented a fast, precise printing process that may make such electronic surfaces an inexpensive reality. The stamp is made from forests of carbon nanotubes and can print electronic inks onto rigid and flexible surfaces. The stamping process should be able to print transistors small enough to control individual pixels in high-resolution displays and touchscreens. It could also offer a relatively cheap, fast way to manufacture electronic surfaces for as-yet-unknown applications.

Laser-Driven Light Source

Energetiq Technology (Woburn, MA) has introduced its 5th generation, ultra-bright, Laser-Driven Light Source (LDLS™), the EQ-77. The EQ-77 offers higher radiance and irradiance from a truly broadband white light source. The EQ-77 features a compact lamp house, with clean construction that ensures long life and ultimate stability. With a wavelength range from 170nm in the deep ultraviolet to >2µm in the near infrared, and a choice of dual-beam output or a single-beam output with retro-reflector, the EQ-77 is flexible for a broad variety of applications.

Diffuse Reflectance Probe

The Ocean Optics (Dunedin, FL) Diffuse Reflectance Probe (DR-Probe) measures 45° diffuse reflectance, enhancing UV-Vis and NIR spectroscopy results. The DR-Probe integrates a light source and collection optics into one unit. With the probe’s collection optics fixed in place relative to the light source, the measurement geometry is constant. An included standoff accessory ensures a consistent 40 mm focal length between the probe and the sample. The DR-Probe has rugged, all-metal construction for durability, and its 6W tungsten halogen bulb has a 10,000-hour lifetime.

CoaXPress Frame Grabber

Responding to the need to create a cost-effective, high-speed interface to fully leverage CXP cameras, BitFlow (Woburn, MA) has introduced the Aon-CXP single link CoaXPress frame grabber. The Aon is powerful enough to support camera speeds up to 6.25 Gigabits/second, which is almost twice as fast as USB3 and over six times the speed of current offerings of GigE Vision. While capturing video at those speeds, it is simultaneously sending control commands, triggers and up to 13 W of power over a single piece of 75 Ohm coaxial cable.
