4-D imaging with liquid crystal microlenses

Most images captured by a camera lens are flat and two dimensional. Increasingly, 3-D imaging technologies are providing the crucial context of depth for scientific and medical applications. 4-D imaging, which adds information ...

How to expand and contract curved surfaces of all shapes

Researchers at TU Delft's department of Precision and Microsystems Engineering (PME) have designed a dilation method that can be applied to any curved surface. This universal method may have a range of applications, including ...

Researchers capture moving object with ghost imaging

Researchers have developed a way to capture moving objects with the unconventional imaging method known as ghost imaging. The new method could make the imaging technique practical for new applications such as biomedical imaging, ...

Blurry imaging limits clarified thanks to information technology

Although we're told a picture speaks a thousand words, that cliché seriously underestimates the value of a good image. Our understanding of how the world works is simplified by our ability to turn data into images. Imaging ...

Mathematicians' work helps change how people vote

As U.S. courts debate gerrymandering—the process of carving up electoral districts to disproportionately benefit one political party—Wes Pegden's work is helping to shape redistricting maps more fairly.

Hubble captures a dozen Sunburst Arc doppelgangers

Astronomers using the NASA/ESA Hubble Space Telescope have observed a galaxy in the distant regions of the Universe which appears duplicated at least 12 times on the night sky. This unique sight, created by strong gravitational ...

SwRI to plan Pluto orbiter mission

NASA has funded Southwest Research Institute to study the important attributes, feasibility and cost of a possible future Pluto orbiter mission. This study will develop the spacecraft and payload design requirements and make ...
