When measuring with light, the lateral extent of the structures that can be resolved by an optical imaging system is fundamentally diffraction limited. Overcoming this limitation is a topic of great ...

Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused ...

From overcoming classical optical limits to tracking single proteins in real time, super-resolution imaging continues to ...

Researchers have developed a new microscope that can visualize the optical response of surfaces at an unprecedented spatial resolution of one nanometer. This paves the way for optical microscopy of ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...

This article discusses how optical microscopy is used in analyzing, visualizing and imaging nanomaterials as well as its limitations and recent studies related to optical microscopy utilization in ...

Illustration of Remondo’s partial aperture imaging system, or PAIS. WASHINGTON — An Israeli space startup says it has found a way to extract high-resolution imagery from satellites small enough to fit ...
