Researchers demonstrated the first nanophotonic microwave imager chip, which is significantly smaller that the equivalent all-electrical systems with a higher efficiency, and enables realization of hand-held microwave imagers for applications including through-the-wall imaging and tumor detection.

New Chip Can Enable Hand-Held Microwave Imaging

The new imagers could be useful for imaging through walls or detecting tumors through tissue in the body.

Researchers developed a faster strain-temperature sensor that features one million sensing points over a single 10-kilometer of standard fiber. It could be useful for monitoring the integrity of large structures and for biomedical sensing.

Sensor Could Detect Structural Defects Quicker

With one million sensing points, a newly developed fiber optic sensor could offer significantly faster detection of structural problems.
