Choosing Optics for Medical Lasers

Designers of medical equipment using lasers must be careful in their selection of optical components in order to ensure safe and reliable operation. The high power density and narrow wavelength range of lasers create problems not found in other medical optics such as microscopes and cameras. Proper selection of materials, manufacturing specifications, and coatings becomes essential to avoid such problems.

NASA Launches New Technology

A successful NASA flight test this summer showed that a spacecraft returning to Earth can use an inflatable heat shield to slow and protect itself as it enters the atmosphere at hypersonic speeds. This was the first time anyone has successfully flown an inflatable reentry capsule, according to engineers at NASA’s Langley Research Center in Hampton, VA.

Solar Panel Power Optimizer

SunMizerTM from Xandex Solar (Petaluma, CA) is a new per-panel DC-to-DC power optimizer that increases solar energy harvest by recovering power that is lost when shade falls on a panel. SunMizer can be installed selectively - only on the solar panels that experience regular shading or soiling.

Reducing the Cost of Energy in Concentrated Solar Power Systems

Concentrated solar power (CSP) and concentrated photovoltaic (CPV) methodologies generate electricity by focusing a large amount of sunlight onto a much smaller area. To maximize efficiency, the sunlight needs to be accurately focused, and the accuracy is limited by the accuracy of the sensors used. A white paper from US Digital discusses why an absolute inclinometer is the most effective sensor solution.

Hydrogen Reclamation and Reutilization

John C. Stennis Space Center (SSC) provides rocket engine propulsion testing for NASA’s space programs. Since the development of the space shuttle, every Space Shuttle Main Engine (SSME) has undergone acceptance testing at SSC before going to Kennedy Space Center (KSC) for integration into the space shuttle. The SSME is a large cryogenic rocket engine that uses Liquid Hydrogen (LH2) as the fuel. As NASA moves to the new ARES V launch system, the main engines on the new vehicle, as well as the upper stage engine, are currently baselined to be cryogenic rocket engines that will also use LH2. The main rocket engines for the ARES V will be larger than the SSME, while the upper-stage engine will be approximately half that size. As a result, significant quantities of hydrogen will be required during the development, testing, and operation of these rocket engines.

Digital Video Recording and Analysis With Laser Targeting

Munitions accuracy provides an advantage in leveraging and applying force and has been sought after by political and military strategists for decades. Reflecting recent advances in technology, during Gulf Wars I and II, Americans watched video on the news of U.S. precision-guided bombs destroying tanks, flying through windows, and exacting coordinates on bridges utilizing laser-guided targeting. Yet, we forget the past challenges associated with target acquisition and destruction.
