Design, Fabrication, and Test of WFIRST/AFTA GRISM Assembly

Goddard Space Flight Center, Greenbelt, Maryland This work originated with the Wide Field InfraRed Survey Telescope (WFIRST) slitless spectrometer design (GRISM assembly), which attempted to follow the Hubble Space Telescope (HST) method of employing a singleelement GRISM as a slitless spectroscope. However, WFIRST’s field of view (FOV) is ~100x of HST’s wide field camera, and the spectral resolution is ~5x higher with a relatively faster f/8 system. The design turned out to be extremely difficult using only one diffractive surface. Even with many freeform optical elements, and putting a grating on a toroid surface, the image performance was still not satisfactory.

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.

Thermal Imaging Cameras See Through the Smoke

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.

Multi-Screen Imaging

The Transcoder Gateway from Pleora Technologies (Kanata, ON, Canada) transmits GigE Vision and USB3 Vision video to any playback device, including tablets and smartphones. While preserving the high-quality video required for processing and analysis, the image feed is converted into the H.264 compression format and transmitted over a wired or wireless connection using the realtime streaming protocol (RTSP) to a playback device. The image feed can also be saved as IEEE 1588 time-stamped video to USBattached storage media, and output with administrator-specific overlays via an HDMI connection to high-definition displays.
