SCaN Optical Link Assessment Tool Version 2

John H. Glenn Research Center, Cleveland, Ohio In response to the requirements of the Space-Based Relay Study (SBRS) undertaken by NASA in 2013, as well as the Integrated Radio and Optical Communications (iROC) project being conducted by NASA Glenn Research Center (GRC) beginning in 2012, a calculation procedure was required to rapidly assess the operation of optical communication links originating from within deep space (in particular, from around Mars in the case of iROC), as well as within the near-Earth scenarios of LEO and GEO (in the case of SBRS). Such an assessment included the specification of the design components of the optical system to achieve reliable communications as prescribed by one or several metrics that indicate overall system operation. Additionally, it was also desired to be able to dynamically evaluate such optical link operation as the satellite/earth orbital positions evolve during the mission lifetime.

The Dusk of Fire-Wire, The Dawn of USB 3.0: Advancements and critical aspects of camera interfaces for next generation vision systems

Before 2011, many system designs were built on the most popular interface at the time: FireWire. This technology is slowly becoming obsolete and is commonly being replaced by USB 3.0, the new predominant interface for industrial and scientific cameras. In this paper we will outline why people are making the upgrade from FireWire to the USB 3.0 interface, and why USB 3.0 is here to stay.

THz-TDS and THZ-FDS Imaging Systems

Terasense (San Jose, CA), in collaboration with Toptica Photonics (Victor, NY), has unveiled the first imaging cameras enhanced for time-domain and frequency-domain generation systems. The new cameras, developed for specific use in TDS and FDS systems, operate in the 50 GHz to 0.7 THz frequency range. Both products achieve 50 fps and pixel size dimension of up to 1.5 × 1.5 mm2. Image test results achieved are publicly available on the Terasense website for further analysis and inspection of realtime application. For Free Info Visit http://info.hotims.com/61057-205

Infrared Cameras

Xenics (Leuven, Belgium) offers the Cheetah-640-CL SWIR camera. The new 800-Hz version outputs 12-bit images via a standard CameraLink medium interface. A TE1-cooled sensor allows the Cheetah-640-CL to achieve low dark current characteristics from 1 μs up to 40 ms @ 25°C sensor temperature (high gain mode), or up to 100 ms @ 268K sensor temperature (high gain mode). The camera obtains above 1000 frames per second at 640×512 resolution. The device is currently being used in adaptive optics systems to correct imaging systems for atmosphere turbulence.
