Choosing the Right Camera for Thermography Projects

Infrared (IR) thermography is an indispensable tool for studying dynamic thermal phenomena. This type of imaging is accomplished with an IR camera (Figure 1) that converts infrared radiation into a visual image depicting temperature variations across an object or scene. In addition, a good IR camera makes accurate (±1°C to ±2°C) non-contact measurements of the object’s temperatures.

Micro-Molded Spacers Protect Thermal Insulation of Cryogenic Propellants

Micro-Molded IMLI Matrix part Phillips Plastics Corp. Prescott, WI 877-508-0252 http://phillipsplastics.com To achieve a high level of energy density as well as green environmental performance and safety, NASA prefers to use cryogenic propellants such as liquid oxygen, hydrogen, and methane to propel their spacecraft. However, these propellants are at very cold temperatures, as low as -423°F, and must be stored in thermally insulated tanks to keep the contents from boiling off. Next-generation NASA exploration missions will require spacecraft such as the Altair Lunar Lander to maintain cryogenic propellants for up to six months.

Lenses Monitor Hubble Space Telescope Servicing in Orbit

C-mount Xenoplan and Cinegon lenses Schneider Optics Van Nuys, CA 818-766-3715 www.schneideroptics.com Schneider Optics’ C-mount Xenoplan and Cinegon lenses were selected by NASA to monitor aspects of the recent Hubble Space Telescope servicing mission. During the rendezvous between the shuttle Atlantis and the Hubble Space Telescope, and thereafter — while seven astronauts replaced six gyroscopes, batteries, and a sensor used to guide the telescope — the lenses were the “eyes” of the cameras that delivered high-resolution images to the shuttle and to engineers on Earth.

Disk Lasers in the Photovoltaic Industry

Diverse types of lasers, such as nanosecond, pulsed, and excimer, have been considered for various applications in the photovoltaic industry, including edge isolation, edge deletion, drilling for back contact, cutting of Si-wafer, and patterning of crystalline solar cells. High power lasers, with high stability and high efficiency in addition to high beam quality, are needed now more than ever.

NASA Research Will Help Aircraft Avoid Ocean Storms and Turbulence

NASA is funding the development of a prototype system to provide aircraft with updates about severe storms and turbulence as they fly across remote ocean regions. Scientists at the National Center for Atmospheric Research (NCAR) in Boulder, CO — in partnership with the University of Wisconsin — are developing a system that combines satellite data and computer weather models with artificial intelligence techniques.
