The International X-ray Project seeks to build an x-ray telescope using thousands of pieces of thin and flexible glass mirror segments. Each mirror segment must be bonded into a housing in nearly perfect optical alignment without distortion. Forces greater than 0.001 Newton, or...

Free-space optical communication holds great promise for future space missions requiring high data rates. For data communication in deep space, the current architecture employs pulse position modulation (PPM). In this scheme, the light is transmitted and detected as pulses within...

For many aspheric and freeform optical components, existing interferometric solutions require a custom computer-generated hologram (CGH) to characterize the part. The overall objective of this research is to develop hardware and a procedure to produce...

A high-speed edge-detecting line scan smart camera was developed. The camera is designed to operate as a component in a NASA Glenn Research Center developed inlet shock detection system. The inlet shock is detected by projecting a laser sheet through the airflow. The shock within the airflow is the...

NASA has identified deep-space optical communications links as an integral part of a unified space communication network in order to provide data rates in excess of 100 Mb/s. The distances and limited power inherent in a deep-space optical downlink necessitate the use of photon-counting detectors and a...

The thermal infrared sensor (TIRS) is a quantum well infrared photodetector (QWIP)-based instrument intended to supplement the Operational Land Imager (OLI) for the Landsat Data Continuity Mission (LDCM). The TIRS instrument is a far-infrared imager operating in the...

Last week, a space startup called Planetary Resources announced its plan for the future: asteroid mining. With diminishing resources on Earth, the company's founders believe that space offers the next logical frontier. They will use small satellites to scan near-Earth asteroids for rare materials, perhaps...

This issue of COMSOL News showcases how a number of leading scientific, engineering, and medical organizations from a broad range of industries are reaping the benefits of multiphysics simulation in their research and development processes. Download the digital version (PDF) at right to learn about COMSOL News outlined in the...

Researchers at the Fraunhofer Institute in Germany have developed new software that can be used to analyze and optimize transport grids for electricity, gas, and water, even at the planning stage, based on numerical simulations. This can lighten the tasks of retrofitting and expansion, save energy...

All over the country, millions of Americans still live behind dams or levees, and if these were to fail and unleash catastrophic flooding, as some did in New Orleans in 2005, property and life might once again pay the price. Answers to at least some of the problem are now on the way,...
