Creating Advanced Dosimeters Requires Thorough Inspection of Small Components

The McMaster University students will launch the small satellite into low Earth orbit to study the effects of ionizing radiation on the human body. Recent advancements in space technology have resulted in space exploration becoming a rapidly growing field, and the desire for human space exploration is drastically increasing. Previous manned missions include flights to low Earth orbit (LEO), such as to the International Space Station (ISS); however, upcoming flights are planned to go beyond LEO, such as to asteroids and eventually Mars. A major consideration in such missions is that the space environment is significantly different from that of Earth, especially with respect to the radiation environment. This drastic difference results in concerns regarding radiation dose.

A Solar System Internet

NASA has taken a major step toward creating a Solar System Internet by establishing operational Delay/Disruption Tolerant Networking (DTN) service on the International Space Station (ISS). The DTN service will help automate and improve data availability for space station experimenters, and will result in more efficient bandwidth utilization and more data return.

3D Imaging Laser System

The system achieves high-resolution, real-time, three-dimensional imaging using an innovative single lens system. Goddard Space Flight Center, Greenbelt, Maryland NASA’s Goddard Space Flight Center has developed a non-scanning, 3D imaging laser system that uses a simple lens system to simultaneously generate a one-dimensional or two-dimensional array of optical (light) spots to illuminate an object, surface, or image to generate a topographic profile.

High-Speed Edge-Detecting Circuit for Use with Linear Image Sensor

Applications include supersonic jets, manufacturing, lane line tracking for vehicle control, bar code scanners, and digital photography. John H. Glenn Research Center, Cleveland, Ohio A new smart camera developed at NASA’s Glenn Research Center has the ability to process and transmit valuable edge location data for the images that it captures — at a rate of over 900 frames per second. The camera was designed to operate as a component in an inlet shock detection system for supersonic jets. A supersonic jet cannot function properly unless the airflow entering the machine is compressed and slowed to subsonic speed in the inlet before it reaches the engine. When supersonic air is compressed, it forms shock waves that can destroy the turbofan and surrounding components unless they are pinpointed and adjusted. This smart camera uses an edge detection signal processing circuit to determine the exact location of shock waves, and sends the location information via an onboard microcontroller or external digital interface. This highly customizable camera’s ability to quickly identify precise location data makes it ideal for a variety of other applications where high-speed edge detection is needed.

Methods of Real-Time Image Enhancement of Flash LIDAR Data and Navigating a Vehicle Using Flash LIDAR Data

Applications include robotic ground vehicle collision avoidance, topographical/terrain mapping, and automotive adaptive cruise control. Langley Research Center, Hampton, Virginia The original (left) and enhanced resolution Flash LIDAR images. NASA’s Langley Research Center has developed 3D imaging technologies (Flash LIDAR) for real-time terrain mapping and synthetic vision-based navigation. To take advantage of the information inherent in a sequence of 3D images acquired at video rates, NASA Langley has also developed an embedded image-processing algorithm that can simultaneously correct, enhance, and derive relative motion by processing this image sequence into a high-resolution 3D synthetic image. Traditional scanning LIDAR techniques generate an image frame by raster scanning an image one laser pulse per pixel at a time, whereas Flash LIDAR acquires an image much like an ordinary camera, generating an image using a single laser pulse. The benefits of the Flash LIDAR technique and the corresponding image-to-image processing enable autonomous vision-based guidance and control for robotic systems. The current algorithm offers up to eight times image resolution enhancement, as well as a 6-degree-of-freedom state vector of motion in the image frame.

Spatially Aberrated Spectral Filtering for High-Performance Spectral Imaging

This innovation has application in the biomedical research, semiconductor, and analysis/characterization fields. NASA’s Jet Propulsion Laboratory, Pasadena, California High-performance thermal imagers like Mars Climate Sounder (MCS) on the Mars Reconnaissance Orbiter (MRO) and the Diviner Lunar Radiometer Experiment on the Lunar Reconnaissance Orbiter (LRO) currently use a three-mirror anastigmat (TMA) optical design to image remote targets. A TMA telescope is built with three curved mirrors, enabling it to minimize all three main optical aberrations: spherical aberration, coma, and astigmatism. This is primarily used to enable wide fields of view, much larger than possible with telescopes with just one or two curved surfaces.
